It's December, which means you are already late on your Christmas cards. If you'll be writing your end-of-year letter on behalf of yourself, your partner, and maybe your kids, start thinking about your return address.
Of course, if you want to go crazy, sure, be the Joneseseses. What are your friends going to do, send the card back?
If your family doesn't all share the same last name, things get more complicated fun. You can go with "the Nguyen and Le family," make a fake hyphenate, or just list everyone's full name like you're a TV show's opening credits.
Or you can turn your names into a celebrity portmanteau, like the Rodrigautistas, or the Smicksons. My wife Rachel Fershleiser and I call ourselves the Dougleisers. Most results sound like a pharmaceutical, but people find it cute.
Just please don't put an apostrophe in there, or you'll make a lot of pedants twitch.
