I love sleep too, but dang

Every single night that my roomate stays up past 12, he sleeps until at least 2 pm the next day. I have no problem with this most of the time because I can just go do my own thing. But, if I want to play guitar, watch tv, listen to music from my computer, or play video games, I wait so I don't wake him up. It's just common courtesy. Still sometimes I wish he had a normal sleep schedule so that I could get more done without having to worry about waking him up.
