I use about 75 - 100 of my 450 "anytime" minutes each month, and maybe another 60 or so night & weekend/m2m minutes. Not a big phone talker.
But yes, I do hate it when people call just to waste time. I'd rather just wait until I see them, so that then we have something to talk about. Or, if I don't see them very often, have a longer conversation every few weeks.
