This quote is very special to me.

Some nine years ago, when I was a tour guide at the United Nations headquarters in New York City, a colleague of mine brought a piece of cloth that he had picked up from the visitors area. Apparently, one of  the tourists had forgotten it or actively left it there. My colleague asked if any of us would like to hold on to it in case the tourist came back looking for it. I volunteered to be the steward of this cloth until its owner returned.
