The lost art of charm

Dating and hooking up is a game. It's figuring out how to play and who to play with that either makes you winner or loser.  I have run across more than my fair share of winners and losers of the game over the years.  Often times I wonder when will guys figure it out? 

Although my actual one-on-one dating experience is quite limited (I've been married since I was literally a teenager) I have been approached, hit on, flirted with, and  propositioned more times than I care to count.  Are there winners and losers in a game with the already spoken for? Always.
