The cousins, Fleur and Jasmine, have a tendency to intentionally or accidentally leave things the other enjoyed. Most of the time it is a accidental situation. I failed to ensure everything that was brought is accounted for before walking out the door.
The intentional happened often enough the girls started rationalizing the other intended it to be left. Which is maybe for the best.
It usually makes it home the next week. And both have enough one thing is probably not missed too much. And if that one thing is a favorite they move on to a new one in the week.
Just a year ago, Fleur would meltdown over leaving something somewhere. She has quadruplet cheap dolls because of leaving the first somewhere. Often enough in the past year she would get upset over forgetting to bring a toy.
