It is fun to be a girl.
It is fun to hang out with girls.
It is hard to be a girl at an engineering school.
The guys at an engineering school tend to think of you in two ways:
1. Oooooh! a girl!
2. One of the guys.
So one needs to hang out with other girls occasionally so as to not get lost in math, and computing, and statistics, and papers, and problem solving.
Fortunately, I live with a girl and next to another house full of girls.
We brought them cupcakes this evening and had fun discussing girl things.
And laughing at the guys (C. S. Lewis was right in his assumption - that is what we do when we get together).
We have a lot of amusing guy friends.
