omg I am a dumbass. -_-
My brother has a friend who sometimes mentions to others that I'm trans (not appreciated, because I even spoke with him about it). So one of these girls who was told came to visit, and I don't think she picked up on me being trans. She just was like "wow...you're way shorter than your brother" and was surprised that I was the older one as well. So, I guess maybe she didn't make the connection that I was the transgender one. But I let the laptop fall asleep with Susan's pulled up, and they borrowed it to order pizza while I was napping. So my carelessness eradicated any doubt she may have had. If I'm going to be stealth in the future, I will have to be more conscientious of this stuff.
