Hmm...being watched. It seems I'm usually the one doing the people watching, but yes I think I usually notice it when an individual is watching me. I think I'm "noticed" more than "watched" though, like in passing people's facial expressions usually change when they see me. Some grimace, some tilt their head, some widen their eyes but an expression usually happens. I agree with @Honor though that an individual watching me doesn't really bother me, and even sort of intrigues me (perhaps because I do it to other people). I don't think I've ever acknowledged the watcher, though perhaps I should because I want to know what they are thinking. Is it similar to what I think when I watch people?
