And now there are down votes and all kinds of assumptions about me and what I intended. I don't know why that is. Given the context of my remark, it should be obvious that my only intent was to rebut someone basically talking trash about me.
It isn't manipulative to spend 45 minutes talking to someone because you are lonely or you are genuinely interested in them or they happened to say "hi" and you happen to be a chatty sort. But the world would be a vastly better place if this were not routinely mistaken for being more than it is. People routinely act like "It engendered feelings in me, so this must be True Love (or you must be my new BFF)!" And that tends to go bad places because neither person knows the other well enough for it to actually be the basis for a serious relationship. Then folks get married or pregnant or start imposing expectations on the other party that the other party did not expect and does not want and the result is usually some kind of drama.
Healthy relationships take some time to feel out. Jumping into things tends to go bad places.
Pick up artists know that many people are not that socially and emotionally savvy and they take advantage of it. I know that many people are not that socially and emotionally savvy and I try to educate people in hopes of seeing a down tick of general drama in the world at large.
