There are the folks downstairs who like to smoke, um "sandwiches" (thanks, HIMYM!). Occasionally the wind blows the right way when they're outside and we end up closing up for a bit to avoid the contact high. This week though, I think he's been lighting up sandwiches around 8a, daily. It's possible that's always been true and I just didn't have my window open, or he has a room in the apartment for such things in bad weather but jeesh, it seems excessive to me.
In another direction are the neighbors who've been working on some kind of construction project that involves what sounds like a table saw at odd times. They're out there currently listening to a Peter Cetera CD. On repeat. The same CD they listened to last weekend. Also on repeat. Would buying them a new CD be rude? Wait, they may have just moved on. That sounds new. It's "25 or 6 to 4" by Chicago. So, baby steps I guess.
