Flirting
You see, it is all about intent.
It has been stated that flirting is indistinguishable from any other compliment that you would pay some one. A compliment is just that a compliment. Once uttered, heard or not, it falls to the floor, its purpose fulfilled. Answer this, when was the last time you witnessed a self professed “flirt” compliment an unattractive complete stranger without wanting something from them? The greasy mechanic that wants to charge more than one is willing to pay is the easy choice. How about the nerdy guy at the electronics store? Or maybe the sales guy at the cell phone kiosk? When was the last time you witnessed the flirt compliment someone with out gaining a single thing for it?
What’s the difference? A flirtatious comment is loaded with intent. What intent? Easy, to further the time spent with the flirtee in an effort to further the relationship along. Whatever the nature if the relationship may be or however a beneficial outcome will aid the flirt is the ultimate goal of flirting. They flirt to gain something.
You can compliment a person on something and that is that. You don't care if they hear it, or accept it, or even acknowledge it, though one would expect that they do at least acknowledge it. However, if you are flirting, the very weight behind the compliment is delivered as well, and that amount of investment becomes important. If it goes by unacknowledged the flirter is a tad put off. The prize is eluding them. Their hard work or witty efforts are being rebuffed. The flirt has to have their comments accepted.
Would you like to know why? Without the acceptance of the comment they are not allowed to continue on to the next level. They are shut out on the spot and will most likely try again with a little more vigor or they will move on. For what purpose is there the need to go to another "level" if not to hope for an opportunity at something else? I wonder what that "something else" could be if the recipient is not their current partner. What possible gain could they desire to make if not to spend more time with their quarry?
This does not mean that one cannot engage in a lively conversation with someone. It simply means that if you do, that you have no desire to get any specific outcome for having the conversation. Talk all you want, but be careful.
If you are in a relationship, respect the relationship. Any desire to get into someone's pants should be directed at your partner and flirting directs your attentions, and intentions, elsewhere.
