Most Helpful Guy
Perhaps he's like that, but I don't do that ridiculous number-rating at all. Of course I notice when I'm around an attractive woman, but that's automatic and requires no conscious effort, I'm sure you see guys in a similar way. I don't really see the point in constantly comparing women to other women.
And even if that friend of yours hands out a number, that number says more about him than about the girls that have been 'judged'. Attraction and beauty are mostly in the eye of the beholder. For example, my best friend's preferences differ quite a lot from mine.
Your friend sounds rather shallow.
