Entrepreneur

Ostin is an entrepreneur in the making. He has been coming home from school with acorns. He wants to plant them to grow a tree. Today, he came home with a pocket full of them. He sold "sand balls" (I don't know but can guess what these are) for an acorn each. I'm somewhat amused that he had the other kids looking for acorns to buy a "sand ball" from him, so he just collected the acorns from them.
