Mine is: I was filling up my horses' water trough this morning with the hose. Toby thought it looked interesting, so he came for a drink of water. He put his nose up to the stream of water from the hose, and played with it for a minute with his nose. You know the cute thing where they wiggle their lips around? Yeah, that's what he was doing. So simple, but cute nonetheless.
Anybody want to share theirs?
