I almost started typing a well thought out response, but I said fuck it.
What are you doing living with people who are up that time still?
Freshman year of college I would wake up to the sound of my dumbass roommates computer going off at 4am for his ROTC training...then he'd hit snooze. Its fucken annoying.
I'd go nuts. I have enough trouble sleeping as it is. Anyone who actually wakes me up once I've fallen asleep better have a DAMN good reason or I will lose my shit.
