When we went to church we had a full bag of unbroken, straight from the box, crayons. When we came they were all broken in half. I was quite frustrated that my girls had broken all of their crayons, obviously on perhaps. During interrogation I finally got Cassie to fess up, "I broke them in half so that Chloe could have the same color as me at the same time!" I guess that's how I have taught them to be with other things, so why not crayons?
