Ok a war box extreme, but a few things for a power cut that lasts hours, being snowed in and not having to risk broken bones to go to the shops. Another lock down. The family having flu/sickness bug/etc. Forgetting to get meat out of the freezer. Someone losing a job or sudden bills that hinder cash fliw
having some essentials loo roll, uht milk, extra tea coffee, tins of food, pasta, rice, microwave meals, cleaning products, soap, washing powders.
I was brought up with not a lot of money, when we were flush mum and dad bought extra "it won't eat or drink in the cupboard" my dad used to say...ie it doesn't cost us anything to have in.
we have come close to being flooded with sewage, the house being completely surrounded by a puddle of it. I have a go bag so if we have to get out of dodge we have toiletries, underwear, snacks, touches etc.
better safe than sorry
