Flirting too much?

It's come to my attention tonight that I have this issue with flirting. Specifically, that I do it too much, even when I don't want to.

I'm not doing it overtly, in the form of comments or anything. I just have this issue where...I kinda smile too much, or I touch people a little too casually, and too often.

It's not even that I really am that attracted to them, or anything. If I even recognize them as fairly attractive people, it happens.

I hate it. It's really an unconscious thing; a bit like being too nice and letting people walk all over you. I smile at people too much like I'm trying to say, "Hey, you're not too bad."

I probably make myself look like a complete idiot.
