Millennials have it rough, or so it seems based on conversations in story meetings (and personal observations of my own 23-year-old daughter). They can't, apparently, balance their own checkbooks, write in cursive, get their own health insurance before they're 26 or leave large areas of skin unadorned. Now I'm hearing they can't party like grown-ups.

I can't imagine. But then I was the one in college who created Chinese dinners for 12, threw cocktail parties with honest-to-God booze and knew that the snack bar was a good source for cheese when the fondue pot ran low. Hosting a dinner party was my idea of entertainment in my 20s and 30s. If dessert was followed by boozy dancing to early B-52s, I knew the evening was a success.

I'm not sure what would count as early B-52s now (Frankie Cosmos? Fitz and The Tantrums? Really late B-52s?). But one thing remains unchanged: A party, be it a beer blowout for 100 or a posh dinner for eight, is sort of a contract between you, the host and your guests. You all agree, for at least a few hours, to try to be your better selves: more sparkling, more tolerant, more helpful, more creative, friendlier.

Contracts, however, often seem meant to be broken. Hosts need to work hard to minimize that possibility by being prepared for whoever shows up. I'm 57, going on 58, and I've seen some beauts come through my door. You will too. Trust me.

Given this is the holiday season and the pressure will be on to host a party, here are some tips and suggestions to help you throw a proper do.

Send a real invitation. Emails are fine for very casual get-togethers. For more important or formal entertaining, consider writing out and mailing an invitation. Yes, you'll have to buy stamps, but you can do that online. Imagine the impact when your invite arrives in the mail amid all the circulars and bills. It will immediately stand out. However you decide to extend the invitation, make sure all particulars are listed: where, when, why and whether you expect your guests to bring anything. (I don't, but that's the control freak in me; I want to plan the experience.) Be very, very clear about what they can or can't wear. No jeans at your sit-down dinner for 12? Tell 'em upfront — but be realistic; know your friends. You also might want to give prospective guests a sneak peek at the menu, so those with dietary restrictions can alert you if there's an issue. (Even so, make sure there are some vegan and/or vegetarian dishes on the menu.) Ask guests to RSVP and set a date by which to respond; an email will work fine for that.

Shop in advance. Buy the liquor, beer, wine and soda ahead of time and store in a cool, dark place, preferably a location you can lock up, so roommates can't get at your stash. If it's cold out and you have a secure outdoor area, stow the beverages there a few hours before the party begins, instead of clogging the refrigerator. Just remember to keep an eye on it, so nothing freezes or wanders off. How much to buy? Depends on how much you and your friends drink; be honest in estimating. (At a multicourse dinner party, I generally count on the equivalent of one bottle of wine per person, if all that's being drunk is wine.) Decide on your menu ahead of time too. Look to offer a combination of dishes you can easily and cheaply make in advance with ready-to-eat items picked up at the supermarket or ordered in from a restaurant. Absolutely avoid anything that requires last-minute cooking or preparation, and that includes outdoor grilling, because no one wants to wait around for half-cooked burgers rushed to the table reeking of charcoal starter.

Rearrange your space, if necessary, for the party. I adhere to the Sit Your Butt Down school of interior decorating, meaning that when I feel the urge to sit down, I sit down. There better be a chair or sofa there. Ditto for tables. I want to be able to put down a drink or a dish, safely, on a table without having to go in search of one. So, walk around your space, drink in hand. Think about where people are going to want to gather and think about where you'd want to sit if you were a guest at your own party. Is there a seat there? Make it so; even a folding chair will do. At the same time, make sure you don't clog entries or pass-throughs with too much seating.

Make eating easy. Write up identification tags for the food so guests know what they're eating. If you are feeling especially conscientious, you might want to note which dishes are gluten-free or vegetarian or contain nuts or meat. Assemble the platters and bowls and serving utensils you'll need to properly present your menu. Make sure you have enough plates, cups and cutlery for your guests. I have always loved real plates and metal cutlery, but paper and plastic work too. Have lots and lots of napkins.

Be prepared for smokers (and vapers). Today, people are less tolerant of smoking. It's understandable, but the thoughtful host still tries to accommodate guests. Don't just hand them an ashtray and point to the street, unless your building has a no-smoking policy. The perfect guest will likely insist on going outside anyway, but you should be ready for the less-than-perfect partyer. Can you gussy up a back porch or set aside a little-used guest room for smokers? Do make sure any butts are fully extinguished before throwing them in the trash.

Put away the phones. This sounds great in theory, but good luck getting people to actually do it. Perhaps the best strategy is an age-old one: distraction. Get any guests glued to the phone to start talking with you and with other guests. You might even want to take them gently by the arm and walk them over to the snack table or the bar — anything that will focus their attention back on the party.

Drink responsibly. Offer a lot of nonalcoholic beverages. Gently redirect those who are overindulging to other pursuits like eating or sleeping. Keep the telephone number for a cab company handy. Or you might want to sign up for the various app-based ride services so that you can smoothly cover the cost for a woozy guest (just remember to politely ask for reimbursement later). Take it easy on the drinks yourself; you want to stay fairly alert and sober to tend to your guests.
