Faithful or Crazy??

There is a gentleman who comes to the library and will sit and read to himself. It sounds as if he is reading scripture of some sort of religious importance. I see him walking from here to there and he's always in the undergraduate library or at the law school library. Its very interesting and whatever he's doing, he's clearly devoted. I sometimes want to interrupt him and ask what he's doing. Other times I just think maybe this guy is crazy. Regardless, this guy clearly belevies in something and thats usually something worth noting.
