Jane and I started the dinosaur puzzle (100 pieces) yesterday afternoon. I received a phone call and by the time I was off 15 minutes later, she’d completed the dinosaur puzzle and started and finished the dolphin puzzle (60 pieces). I commented on how quickly she’d done them and she said “I’m so fast because I’m very expert of puzzles.” [she uses “of” as her default preposition these days] And then this morning she started the dragon puzzle (200 pieces), so I guess we’re in another puzzle phase.
