“I was abused when I was three years old for the first time. So, I know what it is to have to deal with that all your life. I’m 74 now.”
That's actually really sad that they've internalized their trauma as something normal. This is why counseling should be mandatory for kids and child molesters should be flayed.
I have the same problem. I work in IT and when I was on the help desk I was one of the "go to" people if someone needed help with a call. There were a couple times I heard new hires complain that I was "mansplaining" to them because I never knew where someone was coming from in terms of technical ability so when I answered their question I began at the beginning to make sure they understood. I did the same thing regardless of gender but I can see how someone felt like I was being condescending if they weren't familiar with me. It did always seem like it was people who didn't want to be there that would complain about it too. On the other hand several people that went on to get promoted off the help desk sent me thank you notes for teaching them so much so it kind of balanced out.
