Is it just me, or does anyone else suffer from a pantry thief? I think mine are aged about 6, 9, & 12 and can smell a box of snacks a mile away. They are not bothered about the box being closed, will break into it anyway they can, exits the pantry with guilty looks on their faces, crumbs on their lips and the quick "I didn't do it" reply when questioned about who ate the snacks.
