I do stare at people sometimes. For the most part I just go with it and let people think what they want. There have been a few occasions where I have felt bad. For example, if the person I'm staring at just happens to be in a wheelchair and I don't want them to feel insecure and think I'm staring because of that, which is totally not the reason I was staring it's just because they happened to be the person closest to me. Other than things like that I don't consider this too much of a problem since I have stopped caring what people think of me. I suppose it could cause problems in trying to make friends though but my only in-person friend is also on the spectrum so she understands.
