When did guys decide that not saying something is the way to go? Is it some kind of lesson that they're taught at a young age that girls seem to miss out on or something?

I've said it before and I'll say it again... you're not being the good guy by not saying it. It's easier on everyone to just get it over with. As far as I'm concerned, avoiding things prolongs the inevitable. I've played it both ways in the past and I've learned my lesson. It doesn't necessarily feel very good at the time, letting someone down, but it's easier than coming up with excuses time and time again while you wait for someone to get the hint. Just get it over with, guys.

You've got the balls, use them.
