different girls find different type of guys attractive...skinny, big, muscular, average, athletic, mustache, scruff, short, tall, etc. Most girls(mature girls, generally a college girl and above) actually care about the guys personality or at least that's my female friends say. Its worth giving a smile, they might just come and talk to you and want to be friends, that way you can meet her other friends. This is a really good way to find your girl. or at least better than nothing.
