I tried not to let my face convey that I didn’t find any of that particularly convincing. I’m not a parent myself, but I’m fairly confident that wherever you find grown-ups with a secret safe where they keep the dangerous stuff, you will find kids who figured out how to open that safe within days of its installation. I’m also confident that mice have been finding their way in and out of mouse-proof containers since before humans ever thought to keep them as pets.
