If our towns and villages go into lockdown which is looking more and more likely or if one of you in the house gets confirmed as having it the whole family has to go into self isolation in that house .... one of you can't pop to the shops for everyone else or go visit grandma to check she's ok so do make sure you have a few weeks of whatever makes your life bearable for however many weeks it may be. In this house we are always well stocked because we can't always get out or don't want to. So no panicking buying needed here but we have been stocking up for a few weeks now as both of us here are vulnerable. That microwave rice is easy .... it's already cooked so only needs reheating. Tinned fish and bog rolls! It can be longer than two weeks too. If there are a lot of cases in your area people don't all catch it the same day so you could be isolated for a few weeks not just two. Get what you're going to need/want even reading material and be comfortable and safe. My daughter a few miles away is on those prepaid electricity and gas meters so she's put a hundred quid I think in each. If you have a hobby stock up stuff for that too. I read got books I try and make music and upload it ... got everythig I need. That milk that lasts months with refrigeration is a good idea too. I can manage fine without milk and don't of course need sugar. Make a list maybe. and there's always home delivery but from what I hear that's already coming under some strain ... a taxi company might do it for you but I would imagine it'll be pricey.
