Hmmm obviously a ridiculous generalisation made by some young kid who was just shafted by his first love
On the other hand, one of my mates gets to know quite a few girls, but gives them too
much straight away. Turns out to be a big softie and comes across much too desperate. All of them have turned around and said, "nah, you're too much of a good friend" blah blah blah. And I told him he needs to relax and play hard-to-get.
Treat 'em mean, keep 'em keen.
Oh, I do have a book here that I found, "The Arsehole's Guide to Handling Chicks", (seriously I do) I might send it to that guy!
