In between sips of sangria at Australian Katie's dinner party, Cathy and I discuss the horrendous state of our shower now that the temperature in Madrid has dropped. "It's freezing!" I complain. I pout my lips. "Oh aye." Cathy sometimes becomes SuperIrish and these types of phrases slip out. We continue discussing how cold the room is, since shower and bathroom are in fact combined in our humble abode. The window to the bathroom is the bane of all things evil and makes sure that the bathroom is the coldest room in the house. Cathy takes another sip of the sangria, eats a miniature pizza (our favorite things at Katie's dinner party) and then says: "I've been figuring out the physics of it, thinking that if I turned the water down a bit then the gas would be able to heat more of it, and it would make the water hotter." My eyes widen at this suggestion. Cathy could fly space shuttles with that kind of brain.
