Ok, ew, sorry about the header. But really, ask any teenage boy/man what he needs to do to take care of himself on a regular basis, and he'll give you probably a pretty good list (groceries, rent/chores, clothes, music downloads, birthday cards/gifts for family/gf, video games, condoms, put shit away so I don't break it and I can find it later, show up at class, set the alarm...etc). Then ask him how much he's remembered to do or get in the last month. He may be able to name the music and games, but if he's honest he forgot most of the rest. It's one type of risk to forget your gf's birthday card, it's another entirely to forget to bring a rubber.
