The other day Joshua found some pink "tennis balls" I had bought for using in the dryer ( those didn't work out, but that's another story). I found him in living room rolling them across the floor with a pitching motion. " Look mom a baseball stadium!" ( He has quite separated the game from the building). He rolled a few more balls and finally one went where he wanted and he raised his hands up in the air and yelled " GO STEELERS!"
