Input: Text: i got this message out of nowhere from someone i served in the army with. without even thinking i replied with "you son of a bitch, how are you?", as if i was just being playful. but nope. he was insulted and i made an ass out of myself.

i tried to apologize, but i haven't received a message back. i guess my social skills are as bad i was told.

TIFU by accidentally insulting a friend over the phone.
