Patience
This picture is proof that people can grow more patient.
Call me crazy, but I decided to cook with not one, but two little boys the other day. I never cooked anything with my first child when she was under three because I hated the mess. I certainly didn't let her get like this.
This time, however, I didn't really care. I'm so much better at cleaning it all up. Plus, I have both a washing machine and a bathtub, and enough water to use them.
The important thing was that the children had fun and did something together with me.
I used to wonder how patience grew. Change of attitude is key I think.
