Something like that happened to me recently, only it was the mother of one of my friends. I haven't seen my friend for awhile, and he doesn't know I transitioned yet, but we use to be close. His mother is a very sweet lady. She didn't recognize me (or it didn't click who I was), even though she was behind me in line at a store and asked me a question. I hadn't seen her for well over a year, and if she would've recognized me or called me out I would've explained what was going on with me. But she didn't say anything, so I didn't tell her who I was. I felt a little bad about it, but I thought it would be better talking to my friend first before having his mother go and tell him all about me.
