First, the funny business of apartment hunting.
With the release this week of Sony's R-rated "Pineapple Express", I learned I am officially old. My daughter is getting ready to move away to school, and we've been scouring Craigslist for students looking to find a roommate. I showed her a bunch of good possibilities, people looking for a female roommate who is "clean, responsible, hard-working..." and then I found a few looking for someone who is "four-twenty friendly." So, don't laugh, I actually thought this was some hip, new way of saying "24/7 friendly," as in friendly all the time. I thought, "How sweet, they're looking for someone who's really friendly!"
Um, that's not what it means. Apparently, as my daughter pointed out, "four-twenty friendly" means you don't mind if the roommate smokes pot. Here is Snopes.com's take on the term's history. I guess I'm sort of surprised someone would put that in a classified, but I found it in several places like here. I'm not surprised that I still have a lot to learn.
