B-U-S, Tow Truck!!

Michael was picking different vehicles that he wanted to take to bed with him. He had more than enough to choose from, but decided he wanted more than his monster trucks, and informed Mommy and myself that he wanted his bus. So I spelled it out for him, and said "B-U-S, Bus". He tried to spell it, but it sounded more like an "O" instead of a "U", and then he found his tow truck, so he proudly told me "B-U-S, Tow Truck" and showed me the tow truck. Daddy was able to find one of his "B-U-S's", but that wasn't the one he wanted. However, Mommy told him that he could use that one for tonight.
