I'm not a guy so I can't answer that question the way you want me to, but I personally have a thing against girls would are beautiful with my brain. It annoys the crap out of me because they don't care about anyone but themselves. I've dealt with these girls at my school and they are not genuine. Girls who are shy and quiet can make all the difference in the world. When a person is shy and quiet means that they think a lot about other things besides themselves. Usually when girls are quiet is because they actually think about lots of different things. They can also come up as intimidating because I'm very quiet most of the time. I'm not trying to say that I'm better than anyone because I'm not, but I've know some people who are quiet and shy but they turn out to be the best people that have ever entered my life.
