I can't say that the word 'creepy' is really the right word for what the OP is asking about. Weird or off-beat, yes, but not 'creepy'. I reserve that word for what I'd think most people would consider creepy, like stalking and whatnot.
In any case, by the OP's definition I am pretty creepy. I'm very strange and feel as though I'm not wired like most people. I care about things most don't even think about, I do things in ways most don't, and I think my mind just works differently. It makes me feel less alone when I meet people that share at least some of my quirks. I think bonds between people who share rare things like that can be powerful. Plus, weirdos are more fun! ;3
