When people stare at me, I check clothing, check my hair, I make sure that I haven't spilled something on myself and lastly, nothing hanging out my noose. If I find nothing (less often than I like), I stand up, smile and say "hi", to the person in charge.
I've heard a hundred reasons for a stare. Not once has it been because I'm trans.
I don't ever actually know what the munchkins are thinking until "Hi" and sometimes, not even then.
Stephanie, you are a nice looking and slightly paranoid woman. Keep looking good. Ditch the paranoia around children.
Hugs,
