Input: Text: tifu...(first post on reddit, so be nice!) so yesterday as i was leaving my college dorm, i decided to stop by a friends room to see what he was up to. i usually knock before entering but for some reason this time i did not. as i opened the door i was presented with the image of my friend who is completely naked with a semi standing in front of his bed with his roommate standing by him with an open bottle of liquid hand soap. i stared at them for a couple of seconds and they stared back at me in complete silence. no words were spoken as i silently left, awkwardly closing the door behind me.

Tifu by going into a friends room without knocking.
