So my dad sexually abused me when I was little. Brandon knows about it and he's really careful about jokes most the time. The other day he was talking about when he was little he accidentally saw his dad's penis and was traumatized and I was joking asking if it was deformed or something and he said "seriously Marly have you ever seen YOUR dads penis??" He was joking but he quickly realized that I could answer that question honestly. He literally started crying and hugged me. He wouldn't let go and he wouldn't stop saying sorry. I've never seen him cry over something like that. But he was crying and felt terrible for saying something like that.
