How to tell when a very tall man is coming on to you:

1. He stands WAY too close. So close, in fact, that you need to tilt up your head and roll your eyes up so as not to strain your neck.
2. He presses his business card firmly into your palm, reiterating that if you have any more questions or needs. ANY questions or needs - you should call him.
3. His voice lowers and smooths - becomes vaguely Barry Whitesque in it's timbre. And he speaks softly so you have to lean in closer.
4. He is so incredibly obvious about it that even you get it - you who don't get it at any other time, usually causing your girlfriend to elbow you later and demand "What the hell was that?!"
