2008 Envelope Glue Still Works Great

Today I went to the post office to mail some stuff to Pendleton Ward. I included an inventory of all the stuff I was sending, inscribed on a notecard given to me by a bookstore in Marin County in 2008, when I came through to read my novel and my audience was named Pamela and Frances. Anyway, I licked the notecard envelope and the glue still worked great! What an invention.
