Well, that is the thing, its a very trivial thing. Common sense says you dont do that, but from what the majority of college students show, I say there isn't a lot of common sense around here. So, I just leave my radio going and let himself listen two things at once.
As far as sleeping goes, I asked him nicely about the sleep times. He has been good about it since (knock on wood), but I may have to remind him again in the future for all I know. Again, common sense stuff, but from my observations, there isn't much around here.
