Baba's tractor, bob-cat, and combine have been very dirty lately so have had to join Baba in the bath. Last night, Baba wanted me to put water in the lift of his tractor. I told him that water was a liquid thus would run where ever it could and he would need to put a solid in the lift.
We discussed the differences between liquids and solids for a while until I notice Zippy standing in the doorway smirking at me. He asked me if I thought Baba was a little young to understand liquids and solids. I said, "No, that's why I'm saving gas and plasma until he is three."
