I lived in a house with two other guys, there was always an issue at meal times, friends over, ect...
Who is cooking what, who is eating what, who ate the last of what, who paid for what, where is the box of what, there is no coffee, booze, toothpaste, toilet paper... this is all the stuff you are going to hear.
Work schedule, bathroom schedule, sleep schedule, who is coming over until what time, who is cutting the lawn today, why is my favorite coffee mug broken, who forgot to lock the back door. I always watch that show on this night.. partying until 4 am... wtf?!?! simple things that never bothered me before now did.. where is my razor? why is the cap off the toothpaste.. Did you clean the shower after you Jacked? WTF!!!!
I got out of the shower one day and my roomates girl friend was sitting on the couch.. I was the only one home.. WTF?!!? If she was cute I wouldn't have cared... I know I locked the door...
Be prepared..
