We brought the groceries in and Janet put them away. Katie was wandering around the apartment. Later Janet told me that she had bought the cheese but it hadn't been put in any of the bags. No big deal, it happens. She would just tell them the next time she went to the store.
A few days later, and thankfully before Janet went back to the store, we saw Katie with a familiar green cylinder. So that's what happened to the cheese. We couldn't help but laugh.
