Honestly there really isn't that much I really know about Chicha, or Wimpy, or Calbino for that matter.
In the fall of 2003, every morning while walking to my Architectural History class I found a small note on the same window ledge, with a pebble on it. It was always a request to "Please Pray For"…someone. Often they were imploring us to pray for Chicha, and occasionally the request included others. It was an interesting experience to hope to find a note each morning, and it had a curious relationship to another found note collection that I was working on.
I'm not one that prays often, so there was a tinge of guilt being the primary recipient of these anonymous requests. I will say, though, that I have thought of Chicha often over the years and sincerely hope that he or she is doing well.
