Joseph is in Charge of Puzzles

Joseph has been into puzzles for a while, and with all of the rain we have been spending more time inside than out so this week brought much puzzle time. One night as we were working on one together and I was about to place a particular piece into a particular spot, Joseph said "no no mommy I'm working on that one". I explained we were working as a team together on the puzzle, and he said "ok mommy, but I am in charge of puzzles". (as you may recall, Joseph is also in charge of coloring).
