Good old snail mail even. It reads:
I’ve discovered that you have been recently involved with my boyfriend. He told me everything. But he is full of remorse and I’m going to acquit him of his sins.
Believe me I know a lot about you and I am going to screw you, you f–king a—hole!!!
(the name was misspelled in the original letter, explicit words readable in the original letter)
Exactly the type of mail you mail you want to receive. My first thought was that this is going to distract him from his recent split-up but then my second thought was that by the sound of it he had already found a way to distract himself a bit. Lubor himself by the way considers the letter to be far too childish to be even remotely funny.
