I DON'T forward e-mails to people. I really don't. But I feel a little dirty posting this here. It's at my daughter's suggestion--really! I've shown her (she's at Cornell) several interesting things I've learned on this forum and she sent this and suggested I share it with you all. If its been posted before (a search says no, but with this search engine who can tell?) forgive me and close the thread. But without further adieu... The llama song.
