A childhood belief about speaking

Both my parents worked at a hospital, my mom as an ICU nurse, my dad as a biomed tech (fixed hospital equipment). I overheard a lot of hospital gossip because both my parents worked at the same place. Usually it was about doctors. I remember being maybe five or six and I heard my parents talking about some doctor being a "womanizer". This was a word I'd never heard before, but given the medical context, I assumed the logical thing: that he was a doctor who turned men into women (which was something I vaguely knew was possible).

So every year, my parents would take us to the company picnic and they had like a little mini carnival with (crappy) rides, a petting zoo, clowns, live music and a barbecue. Fun stuff. One year I befriended this little girl at the company picnic. Eventually she mentioned that her dad is the same doctor who my mom had called a womanizer. I suddenly got very scared that he was going to find me and "womanize" me. Naturally, I assumed he'd done the same to my new friend, being that she was a girl and I all, so I felt very bad for her. Anyway, I was an idiot.
