Trees Three - Gilson Quote
 

Just out of curiosity, does anyone know where the Gilson quote from Trees Three comes from (e.g., a book, song, etc.)? I was talking about it with my niece today and then did an Internet search and really didn't come up with much...

TFS!

P.S. The quote is "Keep your faith in beautiful things; in the sun when it's hidden, in the spring when it's gone".
