The conversation that I had with her was really heated but I think she mentioned my dad's parents first and then said something about "your grandpa" so I think she was talking about her dad. It was just so heated that I'm not 100% sure which grandpa it was. I do have one memory that came back of touching myself in front of my mom's dad and him chastising me for it but that's it. My mom is also really on about "how close you and grandpa were" but I don't remember being close to him at all once I got out of elementary school. It does seem a little weird and doesn't really add up either way. My fiance looks at that conversation as proof that my mom knows my grandpa was at least capable of something, if not guilty of something, but I don't know.
