No, no, no!!! You never leave your Donettos unattended. If you leave them in the woods the squirrels will get them. Or maybe a Forester.
If you leave them on the landing the landing rats will get them. Won't be anything left but a soggy little piece of cardboard where they licked all the residual chocolate and crumbs off.
Guard your Donettos with your life.
Eh don't leave nothing on the landing ....esp ya caulks as when ya go back to get em ya might juss find those fine upstanding men on the landing have left ya a wee present in them lol.........and it won't be the missing donettos lol
