Ok, around other guys, there's no freaking way were going to start evaluating other dudes. It's just not what we do. And when hanging out with girls, why on earth would we want to encourage you to think that another guy looks better? Ever think the guy you're hanging out with might like you?
Sure, I've grown accustomed to making comments about male actors when my female friends start talking about their features, but it's usually accompanied by a silly accent and a tone of laughter. I guess that's better than getting mad about it.
We just don't judge other guys in that way... Unless he's a freaking bad-ass like Chuck Norris where you can't help but admire his awesomeness...
I dunno, good question, but it ain't happening for this guy. Just not what I do, and I have no reason to.
