Yeah I'm surprised at how few people remember how chaotic living with roommates is. Up until I was about 24 there'd be anywhere from 1-15 people in my house pretty much from 10am to ?.Did you go to college? Live in a party house like this one was?
Back then something could have woke me up, scared the **** out of me and 5 minutes later I am back sleeping for the next 6 hours.
We had a water pipe break on my dorm floor once, my neighbor had to come in my room (we didn't lock our doors) to wake me up because I was sleeping through the fire alarm and it was 10:30 am on a Sunday.
