I have a 30-second rule about running water in our hall bathroom. If I hear it for any longer than that amount of time, I have to drag myself over to investigate. Handwashing is not a simple activity, you understand. It is so easy to become side-tracked. I'm sure we've all experienced the urge to fill the sink with suds to make squishy hand noises with, or give our plastic fruit a bath, or draw dirty soap-circles on the mirror with our fingers.
But Theia is obviously beginning to understand that the bathroom sink is mainly for hygenic purposes. This was demonstrated on my most recent trip to the bathroom when the 30-second rule was broken. I rounded the corner to be greeted with, "I'm just makin' my hair beautiful, Mom".
