Input: Text: well, not today but this happened last year. i was in the miltary as a security forces officer (mp) we were in the gaurdmount room which is a room with two armory windows, where we arm up. basically we wait in line till we are called upon to recieve our weapons. well, i was called upon to get my weapons and aside from receiving my m9, i asked for a radar gun. when i got it, i turned it on and pointed it at my friend who was behind me. i pulled the trigger to make sure it worked and i said " bam! you got cancer now" he then replies " you dick, my dad just died from cancer" i felt terrible because we litterally just had a conversation about his dad passing the week prior. i felt like such a douche i couldn't talk to him or be near him for the rest of the day. bad move man..

TIFU by jokingly telling my buddy he has Cancer, When his father just died of from Cancer
