Not that odd. I abhor my phone ringing at all after about 11pm for basically the same reason. The only two times it's ever happened, it was someone died. And I already hated talking on phones or really having anything to do with them before that. If you call me (well....let's be honest....for ANY reason) you better have something really awesome to tell me. If it's at an unreasonable time..I'm just going to ignore the call completely.
