Three Drinks of Hot Water

Rudy loves to drink hot water from the shower. Emme could care less. Her fun is to help us dry our legs after we get out of the shower. As soon as we step out on the bath mat, Emme begins licking our ankles and calves. She keeps it up until we are dry or we send her out of the bathroom. This is like her duty to help when we take a shower.

Rudy on the other hand loves to drink the hot shower water. As soon as Ken or I step into the shower if the door is unlatched Rudy pushes into the bathroom. Then he pushes his head through the shower curtain at the foot of the bath tub. He waits patiently until we fill our hands with hot shower water and hold them at the edge of the tub. He dips his mouth into our hand and laps up the water. We give him three drinks, our limit. I think he would stay there indefinitely and drink. After three drinks of hot water for Rudy, we go back to our shower and he either curls up on the bath mat or leaves the bathroom in search of other excitement.

Why in the world would Rudy consider three drinks of hot water from the shower a treat?
