Nature or Nuture?

I had a good laugh about this so I thought I would share it. Weston spilled a bowl of popcorn the other day, and since his messes are a typical occurrence around here I didn't react, and either did Weston. Then I watched him as he walked into the kitchen, took the broom out of the pantry, and brought it into the living room to "sweep" up his mess.

Now I don't go sweeping the carpet myself, but he obviously understood that a broom was for cleaning, and someone is obviously picking up after him and it should be him.
