Playing outside

Ryland and Cooper love to play in the backyard. It can be freezing cold and raining, and they still stand at the back door asking to go out. I am really paranoid about the pool, so I am sure to keep an eye on them. I was watching them play today, and I thought they were so humorous. Ryland was digging in the flower pots, and Cooper was rolling around on the ground. Ryland's digging turned to dropping dirt in the pot and then to throwing dirt at Cooper. When I asked him what he was doing, he threw his arms out and said "what?".
