No its not DAD!

The object in question below is Avery's Fun dog cup. It is so named because it has dogs on it and..... well it is quite fun. Last night at dinner Avery asked what the blue thing was. I told him it was a pinkney flange. He said no its not dad. I showed it to Georgia and said "Mom is this a pinkney flange", she agreed it was. Then Avery said no dad it is to keep the water from leaking out. Neither Georgia or I had explained that to him. Sometimes it hurts a little when your three year old one ups you. And for those of you who don't know a pinkney flange is found on most foreign cars and should be changed every time you rotate the air in the tires and have the blinker fluid changed.
