I always say to my wife....See, you leave the door unlocked and any fvucking azshole can walk in. The "guest" hears it and says something like, "Uh the door was unlocked." WTF, you always go into someones house just cause the door wasn't locked. No class move. Closed doors are closed fore a reason. Always knock. Then let them know people get shot for allot less. Next time they knock.
