I was sitting at home the other night when the phone rang. I answered it and it seemed to be a prank caller. I hung up the phone, but after the second call i decided to *69 them and tell them off. The person on the other line was acting crazy, screaming nonsense. Finally i was able to talk to her daughter who informed me that my father had been sleeping with her mother. Needless to say I did not believe her, but after talking to her for a while she started bringing up names of other people who she says my dad slept with, and were friends with. Names which are not common, my Parents are Ethnic (Polish). To make a long story short, I kinda Believe her. I am 27 and my sister, Who knows the whole story, is 26. What do i Do? I am not naive and I see no reason for this person to make this up. I have run through every Conspiracy Theory I can. Apparently this woman is not taking their break up very well and the new girl who my dad (is/was) sleeping with is rubbing it in her face, WHAT DO I DO!
