Honestly its probably all body language. My mom has the same thing. Random people just start telling her everything about their life, because she appears open and friendly. If i'm in public, I usually look miserable (RBF) and have a very specific goal in mind. People don't just walk up to me because its obvious I'm not going to be receptive.
