Attraction

There is a certain type of person that is attracted to me, utterly and completely. I can always pick them out in a group. 

There's a man at my dojo who I see infrequently, but when we have class I can tell he pays attention to everything I say and do. I dont think it's a romantic interest, and he isn't obvious about it, but I know he remembers everything about me. I know it's strange, but I can sense his interest- people would think of it as "romantic chemistry" but it's more "interest chemistry".
