campus vandalism

Vandalism is a severe problem here on the UNM campus. The worst of it is in the men's bathroom in Mitchell Hall. Also, when I use the restroom at CSEL, I always see a written conversation on one of the bathroom stalls. Why can't some people keep their opinions to themselves? If these people want to express their opinions so much, why don't they do it in a more civilized manner? I know that UNM is mainly an academic institution, but I think that vandalism in the men's restrooms gives visitors a very bad impression of our university.
