Look at them and smile...
Really though, they should have a choice in what they do, I think, so I try and keep that in mind. ... and I smile because I know what they are missing and are too blind to see.
Nonetheless it is nice to know that not everyone is blind and for what it is worth, I normally do not find those special people among the masses.
I am exceedingly choosy about who I let get close. I suppose not surprisingly that has contributed to being alone most of my life, still, I don't feel like anyone's dirty little secret so I guess that is good

Perhaps it also helps that I am an exotic flavor, I do not expect to be to everyone's cup of tea...
Hang in there, those worth keeping around are sometimes few and far between but they are out there...
