in the dream my lesson plans were a kanban board

I'm standing in my classroom and the whiteboard has turned into a kanban board, except every card has a tiny little brain attached and they keep asking me where I put them. There's a column called 'persistent memory' and I keep smearing it with glue stick, the real kind, the purple one that dries clear, until all the cards slide right off onto the floor. The kids don't even notice, they're just napping and I'm trying to decide if forgetting on purpose is a feature or a flaw.
