You are much more polite than the person who was much more condescending about my mother. It's fine.

I know for facts my mother never cheated. Mother is at an age I have increasing access to medical records of previous...attempts at children. Which lines up entirely with things my father talked about, and how delighted they were when we were born. Also, my father, for his faults, absolutely could spot another cheater at 50 paces and knew my mother did not.

Also she was like. The only person at home, working in education with long hours and then taking care of us, so if she did cheat, like. Damn, she was really finding the time somehow taking care of terrible twins.
