I can't imagine not having a stock of food. Have done for over 40 years ever since we got snowed in for a week living on a housing estate in Kent!
No one knows what could happen - illness, break a limb and not be able to drive, floods, snowed in etc etc.
We have 2 freezers full of food. Mainly things we have made like curries, stews, shepherds pie etc but also bread, homemade soup, milk, veg, fruit etc. We are both vegetarian so have big bags or sacks of various lentils, chickpeas, different beans. We also have lots of pasta and rice and tinned foods like veg, bakes beans, tomatoes.
We did not have to go shopping for a couple of months after lockdown. We easily have enough food to last over 2 months now
