Uncle Art

My Caterpillar says: "My uncle Art is a guard. He always has at least one eye open for the situation."
I say: "Hello, uh? Can't imagine a butterfly to be a guard. Better it is Uncle John. Who is a very good teacher. Never looses sight of his pupils."
Proposed to the client the first sentence/saying and when I wrote it down here, I started to doubt it and than wrote the second saying down without thinking and now proposed it as well to the client.
By the way > I published in advance, because I am going away for a couple of days.
