Girl Talk Vs. Guy Talk

This reminds me of highschool. Being neither a gay nor a playboy, I hang out most of the time with girls from my school. I chat with them during lunch - which consists of a generous serving of cheesiness, I believe. 

When I started college and moved out from out house to a boarding house in a city, I preferred being alone and spent more time with computers and teaching myself. I rarely interact with classmates and I'd always be in the last row of seats in the classroom.

With things above said, I don't have the experience to either prove or disprove Yuu and Mugi's statements. What do you think? Do guys always think stupid and childish and girls, love and fashion?
