You're Not Locking Eyes
What's harder than approaching a stranger? Approaching a stranger who hasn't acknowledged your existence with even a brief look. "I need to see, by her looking and smiling at me, that she wants me to approach her. If I don't see it, I don't approach," says Anonymous. So next time you think he catches you looking at him, don't look away — hold your stare for a few seconds so he knows you're looking — and that you like what you see.

"If she's flirting with lots of guys. Nothing like a woman who is basically telling everyone in the place that she's open for business with anyone," he says.
