What do you do if you're impressed with a dating prospect in terms of character, educations, shared interests, etc., but the initial chemistry between you is not a homerun. It could go somewhere, but not on the fast-track to romance. Do you act accordingly, move extremely slowly, at the risk of being aloof? Or do you err on the side of protecting them and just say you're not interested?
Maybe the real question is, does chemistry have begin with a clear and unmistakable spark, or is it generated slowly when it's the right person?
