We left the house yesterday to go to the grocery store. When we got home, I went to feed the animals. Oldest son comes running out yelling like someone had a hand cut off. Turns out that before we left for the grocery store, 3-yr-old son washed his hands and an EGG in the bathroom sink, plugged the stopper up, and left the water running. It was that way for more than an hour. No, the sink doesn't have an overflow hole. The overflow is called the floor.
