So, the new computer science building on campus is also the new psychology building. The 3rd and 4th floors are for the psych dept, the 5th and 6th are for CS. Now, the psych dept is largely female, whereas the CS dept largely male. I have often mused about whether this was a psych experiment to see how many psych and CS people pair up.
Today I noticed something else coming out of my CS class. In the elevators to all floors, the CS guys will clump together in the elevator to give the females in the elevator (myself included) as much distance as possible. That amused me to no end.
