One of the great things about kids is that their idea of risk and reward is different than ours. For example, yesterday when I was making lunch for my children I included a cookie. Normally I would just give each child a cookie but we had these big cookies that were left over from Easter and they were too big. So, I took one cookie and it broke it into about six pieces and then split it between the two girls... each one getting three pieces of cookie. You would think they had won the lottery because now they were getting three cookies. Children have very little concept of mass (and you can just forget about quantum mechanics). If someone owed me a dollar and instead gave me four quarters I don't think I'd be any more excited about the money but to a child... that's a definite upgrade.
