When I got home from the hospital today Noah asked me to come play with him in the basement. When I asked him what he wanted to do, Calvin interjected: "Dad, it's super-duper messy." Noah rebutted, "NO, it's really messy. The side with the pole and the basketball is messy, but the side with the tv is clean. If all the toys are out, then it's super-duper messy." Uniformed classification systems are important even to 4 year-olds I guess.
