I'm a FLiRT!

One night my best friend and I were spending the night out on the town. I'm usually a very friendly person so If someone tells me good night, I usually say good night back. I've heard way too many stories about guys assaulting girls because they ignore guys. Anyways, my best friend told me that I'm a flirt and I seek attention. I don't think I seek attention. I don't say hold long conversations or seek compliments from guys. A simple good night or thank you I see as being polite. Maybe its just me.
