A few things about this post. Most of this is a argument about words. We all seem to attach different meanings or visions to the word "AFC". I don't think there's a solid, agreeable definition out there, and if there is one, I haven't seen it articulated.
Good point by xblitz about all girls being different. That's the bottom line. You can't take one thing and generalize it across the board like that when you live in a world full of individuals. For example, I don't like a certain type of music, but someone else might. It's difficult to resolve that except to say that everything must be taken on a case-by-case basis. That being said, I'd probably have to say that the most general statement that might be made as to being AFC is that a guy who seeks approval from a girl for all his actions will likely not get too far with a woman. As for everything else, you can buy her flowers, you can buy her gifts, but if you do it, don't expect anything back from it for goodness sakes! Just do it, and move on. Let her draw whatever she likes from it, but don't in essence expect absolute gratitude from her for doing it.
I think too many guys do stuff that is considered "nice", but then they have all these high expectations from the woman for doing it. I think that's where the AFC stuff comes in. Girls like guys who seem to be somewhat spontaneous in their talk, and not blabbering idiots when it comes to talking to them. That to me is where a lot of the "chemistry" is. If you meet a girl who you can banter back and forth without really thinking and the conversation just flows, then there is certainly going to be a feeling that you two "click", and there is at least some chemistry between you. This translates into some attraction most of the time, and where it goes from there depends on how well you fan the flames.
I was at work today, and I literally went from talking to one girl then another, and then another. All of them were hot, but I'd say I was really only interested in one of them, which is the most difficult one to get (not because she's difficult to get, but because she's the hottest girl I've ever seen). The other ones are about HB7s or 8s (the one that's an 8 is actually pretty hot, and we have great chemistry, and I'm going to be hanging with her every morning because we planned to study together for this exam we have). I just met her too like a few days ago, but we were talking nonstop, and it was great chemistry. I can imagine, however, that I can destroy this pretty quick by becoming sort of pathetic, which I can imagine some guys doing, where they realize that they sort of like the girl and begin to think too much.
Thinking too much can ruin everything. You can't be worried about what you say. That to me is a total AFC move in every meaning of the word. At the same time though, You can't be so uninhibited that you don't know your limits. See, most people I know can't balance these things too well. They tend to go too far in either direction. The key is knowing how much is too much. Easier said than done, and it comes through practice and failures. Nothing works better than being in the field and testing yourself. Most AFCs are too afraid of rejection to take this step, therefore they never learn it.
Anyways, I agree with most of this thread, but the only problem is that people can read it and get the wrong idea.
