My twin and I lived with her now ex-boyfriend years ago. Just the 3 of us. I wasn't home much but when I was, they were fighting.

One day I was in the shower and all 3 of us were home that day. Suddenly the BF comes into the bathroom saying that we needed to talk. I told him to get out now. I didn't look out but I could tell he was sitting on the toilet. He proceeds to talk. I just kept telling him we didn't have anything to talk about right now and that he needed to leave. This was probably about 3 minutes long. Suddenly my sister bursts into the bathroom and yells at him for being in there. He quickly jumps up and runs out.

He thought I was her the entire time. Funny thing is, everything he was saying made me feel like he knew it was me. He never called me her name or gave any indication to he thought I was her. He couldn't see me but I felt incredibly violated. I stood on the other side of the curtain frozen and had my fist ready to punch him if he opened it. I cried afterwards because it freaked me out so bad. We laugh about it now.
