Fritz has become obsessed with water. He is constantly asking for water. He gets excited when he sees a cup of water. He leans over and drink the water in the bathtub. When it rains, we hear a constant “Water, water, water!” from him.
This is a side effect of the Allegra he’s taking. He is afflicted with dry mouth and so water has become his favorite thing. Of course with his increased input, his output has greatly increased. At least we know he’s staying hydrated!
