I tried my arm trick for my nieces at the playground yesterday. I got almost the whole way through until the last sort of untangling. I stood there with pretzel arms saying, "I'm stuck, I'm stuck." My nieces looked at me laughing. Finally the younger one shouted, "Let go" and I did. Tell people you can't meet at 5:30. Put a couch in the middle of the daycare so the kids can't sprint across the room.
