In the car one day we were talking about towns and cities. Lex was naming different places and asking if it is a town or city. After answering a few, I explained to him the difference between the two, in terms of size anyway. He thought about it for a minute and then said, “So it’s like cars are towns and vans are cities?” What a great comparison! Then he got silly and started talking about putting towns in cars and cities in vans and the conversation deteriorated quickly :)
