Admittedly I would not have done this but for Trump-induced fear...
BUT I don't think it's anything but sensible to have stored a few tinned goods, bottles of water and other survival (for maybe 72 hours) bits and bobs (think matches and first aid kit sort of thing) set aside...?
OH is mocking me for being a paranoid redneck hellfire and damnation prepping type - which I am not. Should the end of the world come, I hope it takes me down with it... And really, there's only so much you can prep for in an outer London dinky flat.
But in the (far more likely event) that shit happens, but after a few days things all right themselves again, a few supplies in would surely not go amiss...?
