Well, brainychick, to throw a wrench into it for ya, “asking too many questions” and “overanalyzing” could be separate issues from intellect.
For example, if you’re on a first date with a guy who mentions that he’s late because he just came from a doctor’s appointment, and you start giving him the inquisition about his stool sample, well… that might be a bit much.
Or if a guy says, “You look amazing tonight,” and you wonder if that means that you didn’t look good the last time you went out (since he didn’t mention it), or if perhaps he has some weird sort of foot fetish since you’re wearing sandals on this date whereas you wore loafers on the last date, well… again, too much.
I’m guessing, of course, that you’re perfectly charming and that your questions do not reach beyond the realm of propriety, but you know what? Even if they don’t, you gotta be who you are. If you like talking shit (literally) on a first date, then by golly, you talk shit, and if the fella doesn’t like it, ram your sandaled foot right into his dumb ass.
