What’s on the bus?

My latest fascination is with the Wheels on the Bus song. It’s so catchy. At school we sing about the wheels and the wipers and the driver. At home, mommy likes to make stuff up. Tonight on the bus there were book bags that went “flop flop flop,” bugs that went “buzz, buzz, buzz” and other kids that went “Lexi sit with me, Lexi sit with me, Lexi sit with me.” Mommy’s singing is pretty horrible. She seems to make up lots of words to all different songs all the time. (Or at least that is what daddy tells me). But, I don’t want mommy to feel bad so I just smile and giggle when she sings to me. I wonder what will be on the bus tomorrow?
