What to Do with Money

Lastnight, Daddy got home from a consultant job. He got paid in cash. He handed them to Evan who immediately thew the money over his head and started rolling in it giggling! We cracked up. How did he know this is what one does with money?? We would pick up the bills and Evan would take them back and did the whole thing over and over again. It was like he had seen someone do this before or had been told how to do it.
