Seasonal Water?

My mother came by this morning and sat down at the table with Son #3 while he was having his waffles.  (This seven year old who weighs 45 pounds always has four waffles for breakfast on Saturday.  Where does he put them?)  He finished his orange juice and was still thirsty, so he went to get the jug of water out of the fridge.  Grandma had a look on her face like she was up to no good, so I waited for it.  She asked him, "All I ever see is spring water.  Where's all the water from the other seasons?"

His brow was furrowed while he briefly considered this.  His response:  "I don't know, but I bet summer water is HOT!"  

Good for you, little buddy.
