It's because it brings me in close proximity to the undergraduates.
Yes, I bitch about the law students. I find more than a few of them spoiled and bratty. I hate the way they look at me, or rather look through me. To them, I'm not a real human being; I'm a shadow entity, a piece of the scenery who occasionally infringes on their God-given right to break library rules by telling them they can't eat in the library. But, you know, at least they work hard. I can respect that. As far as I can tell, all the undergrads do is drink, spend their daddy's money, go to frat parties, gossip about each other, and strategically arrange themselves on the shuttle buses so that the people trying to actually get to work have to stand on top of each other.
I used to pass those people every day at Vanderbilt. The rich, thin, perfect people. But they really didn't bother me that much, because I was on my way to one of my honors English classes and I was going to go to grad school and be a brilliant professor. Now I see them walk by, and I think that in five years they'll be working for Daddy's company and driving SUVs that cost more than I make in a year, and where will I be?
