Ella,
You are right, we didn't chose to be trans. From their perspective, maybe that is how they see it or try to understand it. At least it is a friendly curiosity, and that is a great time to educate. I think I would prefer that kind of question to the silence I get a lot. They are afraid to ask the wrong question so they as no questions. It becomes the thing not to be spoken about, and I invited people to ask questions when I came out.
