Courstship Gesturing (commonly called "flirting") is Nature's perfectly healthy way of saying...

A. Look at me, and

B. If you approach me I won't object.

This is necessary because...well, in Nature, when one animal tries to get close to another, its usually because one wants to eat the other. That is a pretty powerful motivation to keep their distance. But...in order to reproduce, two individuals must get close.

Fortunately, Nature has provided a clever way of allowing animals of the same species to get really close despite their natural hesitency. Its called COURTSHIP!

Each species has it own peculiar dance of courtship. Although the steps are largely hard wired in other animals, with humans it can vary a lot. Think of courtship steps as the combination to a lock. If you know how to put in the right numbers in the right order, it works.
