He did not learn this from me.

This morning, Matthew spilled a bowl of dry cereal on the floor.  "Uh-oh!" he cried.  "I spill da ce-we-al!  Dat's okay, I clean it up!"  And to my amazement, he went and got his broom and dustpan.  (Yes, we have child size cleaning tools, purchased when I optimistically imagined my children cheerily cleaning up their own messes.)

"Thank you, Matthew!" I said.  "I like it when you clean up your mess!"

"You welcome," he replied and he efficiently swept all the spilled cereal under the fridge.  "All done!"
