What is big, yellow, noisy, and has 4 wheels? A big cheese! In my hometown, there isn't any train, so like most American school children, I had to ride the bus to school. It was so noisy, especially after school when the children were excited and had so much energy. Now that I think of it, it was strange that I never felt tired or sleepy after school, only in class. lol. Anyway, the bus was so noisy with the school children yelling and screaming that sometimes the bus driver would pull over to stop and yell and us. We would be quiet again and after about 5 minutes, be back to screaming and yelling. Poor bus driver. she must have had such a hard job. I had so much fun on the big cheese.
