My thought about it is is this: flirt your heart out, honey.
Whenever I was single, I lived by the motto "I ain't a playa, I just crush a lot".

I was never the type of chick you'd see on tabledancing to get a guy's attention; but I am (or used to be?) great at the verbal banter and picking up and putting down those oh-so subtle physical cues.
I got to the point where I was like this - It's my life, I've got to live it to it's fullest. I may not be rail thin, but damn it I will have fun, I will flirt and ANY guy would be lucky to be with me, if I choose to be with him.
Now, everyone who is scared to flirt, who thinks they are doing it wrong - ask yourself, what could it hurt and then imagine the fun you can have.
CAUTION: Sometimes flirting after you've been drinking seems like a good idea, but keep in mind sometimes they may be cuter while intoxicated or you might go over the top. Yes, I've done that in the past and it backfired horribly.
HOWEVER, if any guy on the highway followed me - I'd be dialing for the state patrol. LOL.
