Won't Drink Out of Bowls!

 I feed my friend's cat periodically when she's out of town.  Whenever I come by, there's always a little bit of food left in his bowl and plenty of water in each of two bowls.

However, as soon as I enter the house, he comes up for a brief head rub against my closed hand, then dashes excitedly for the bathroom sink and waits for me to turn on the water.  He drinks lots, then jumps down and checks out the new food.  Then runs back for another drink.  I wish it were as easy to make people happy.

This facial expression means "thank you for turning on the faucet."
