Short funny story

Last weekend Caiden and I hit the Acton Discovery museum. After exploring the museum in and out, Caiden discovered a drain outside. He went searching for something to throw in there, and found a stony path. He grabbed a handful of rocks and brought them over to the drain, put them down next to him, and started throwing them in. Within seconds, he had company. Every little boy nearby came over to take part. His rock pile vanished! He looked a little miffed and went to go get more rocks, only to have the same thing happen again. And again. Poor guy, barely got to throw in any himself. He was basically just refilling the pile for the other kids. I couldn't help but laugh.

Look carefully, you can see his rock pile!
