Charles is now obsessed with his puzzles (see here). We put them together over and over. Dad has had to take them away a couple times because Charles was getting too upset. The big problem was that he seemed to think that once assembled, the puzzles are actual toys. He tries to push them around like he does with real toy trucks and it doesn’t work. This makes him very frustrated. I think he’s beginning to figure it out, though - he seems to have stoppped trying to push them across the floor or off the table. But now he fights with the cats - they frequently sit on the puzzles and mess them up!. How can the cats we feed and shelter be so rude?
