Pat told me yesterday morning, he didn't finish his bottle. Left an ounce or so. Elliot was playing on the floor, and Pat picked up the bottle to move it. Elliot caught sight of it, decided he was thirsty at that moment, crawled over and begged for the bottle on all fours like a little calf. Pat gave him a couple gulps like this, and then it was back to playing. What a character.
