A little of column A, a little of column B. I don’t specifically look for the graffiti and I rarely see any anyway. The last graffiti I remember noticing was someone had scrawled “Another brick in the wall” in the grout of the wall tile.
In college there was a bathroom on the top floor of the library that named a girl in one of the sororities, and informed the reader of her talent, and that she was a sure thing. No phone number, but knowing her name and sorority were enough to allow a curious fellow to track her down to test the veracity of the statement. I didn’t, but was friends with a couple guys who did, and evidently it was accurate. At the time I was after someone who I thought had long-term potential, but in retrospect I sort of wish I had investigated it further.
