My mom and I took the twins to the zoo on Tuesday morning, and we visited the petting zoo first. (Owen has a strange infatuation with goats.) So after about twenty minutes, and a lot of strange smelling animals, I said, "Okay guys. Say goodbye; we gotta go."
Owie - looking so disappointed - went up to an old, placid, white goat who was standing alone in the corner, and said, "Bye goat. Call me."
