I would tear it into pieces with my hands.
Fuck you for the anxiety you gave me from getting a letter from a name and address I don’t recognize.
Fuck you for the time you made me waste having to open that letter.
Fuck you for the complete bullshit feeling of finding out that you literally just wrote “hi” and expected that to communicate anything or resolve anything.
I don’t know your stupid douchebag ass, and I don’t want to. Fuck all the way off.
I’m here all pissed off just from imagining that hypothetical. It’s nothing short of disgusting that SOME shitheads think that this is acceptable behavior.
