There is someone like that on the college campus in San Jose. He is old and thin and dirty and has lots of scraggly facial hair. He looks very gentle and looks like he knows a lot, but he never speaks and often goes into fits or passes out. The campus police come with a blanket and a little food for him... which I always thought was a wonderful gesture, telling me that some people still do care. Of course, I always want to try and say something to him but I am afraid that if I do I'll actually find out that he's just crazy. He probably is, but I just can't bear to ruin my image of him.
