When Jason was about 4 to 6 years old, we were eating dinner one night and used the last gallon of milk. The following conversation ensued after the milk bottle was empty.
Dad: "I wish we had a cow so we did not have to go to the store to get more milk."
Jason: "Why wouldn't we need to go to the store to get milk if we had a cow?"
Dad: "Jason, where does milk come from?"
Jason: "From the store."
Dad: "And where does the store get the milk?"
Jason: "From the milk factory."
Just in case you do not know where milk comes from, I am providing this video produced by Indiana's Family of Farmers and made available by Indy with Kids.
