Just a quick question, since I can't do polls (so lame): What time do you feel is too late to receive phone calls in a house that you are sharing a phone line with other roommates?
I guess it depends. 10pm is a good rule of thumb, but I've been known to call up my friends well after that. But those I do call up after 10 are night owls like me.
But I guess when it comes to avarage people, maybe 9:00pm at the latest.
