He has a goal in mind (this REALLY was his idea--down to the bottled water with flavors):
He spends most of his time spinning and running around.
About 10 minutes into it, he said he was ready for a lunch break. After convincing him that he really didn't need to go home but could stay a little longer, he sold two bottles of water and made $3 (they gave him an extra dollar because he's so cute).
That seemed good enough for him and he started walking home, leaving Ian and I to clean up. It's his plan to do this every day. I don't know that I'll make it!
