"Weird Smell"

Yesterday after Nina got on the bus to go to preschool Christian and I were walking back into the house when the following conversation happened...

Christian: "I can't wait until I go back to school so I can ride the bus again..." (He rode the bus with Nina last year)

Me: "Yeah...the bus is fun isn't it..."

Christian: "The bus has a weird smell....I REALLY LIKE that weird smell..."
