What a fascinating specimen

I'm trying my hardest to sound eloquent, to use some decorum, to be vague but still get the idea across. But what is this, my quasi-fascination with a man who I don't really want to be seen with in public? (When do I want to be seen with him, you ask? Read between my prim and appropriate lines, please.) So I ran into him last night, and secretly wondered if he was sort of stalking me, then shied away when he touched me, then didn't really want to talk to him, and wanted him to leave, didn't want anyone to know I know him, but still, I'm fascinated.
