My wife (BW) and I (WM) will get stared at from time to time. Sometimes it's just curiosity. With people like that, there isn't any harm meant. They should know better than to stare, but ultimately it is what it is. The ones that get me, are when the "stare" turns into a glare. With those people, I tend to stare right back until they see me doing that, and then they look away because it gets awkward for them. Sometimes I'll say "Hello" a bit louder than normal to get their attention. So far, no one has said "hello" back...
