Acorns

Never lose a chance of saying a kind word. As Collingwood never saw a vacant place in his estate but he took an acorn out of his pocket and planted it, so deal with your compliments through life. An acorn costs nothing, but it may spread into a prodigious timber.
~William Makepeace Thackeray

In my area, oaks have been dropping acorns abundantly (it's a "mast year"). For Art Thursday, the tiny acorn.
