Dear Acquaintance, Since you moved out of town I've been thinking a lot about the past. Two things come to mind. #1 You should know the reason I broke you and your girlfriend up at the time. It was because she had cyclothymia and depression and she was suicidal and she had an abortion and it was YOUR KID. The second thing? You accused me of stalking you and threatened me with sexual harassment. Now my brother and your sister are good friends. Imagine what would happen if I told your sister? Signed, Your Old Friend.
