Little life advice:
Everyone who says not to set your stove clock or microwave clock because you won't use them and don't look at them anyway is lying.
Set them.
Because sometimes, you will come come from a week away when no one was in your home, and see the stove and microwave clocks blinking and go, "Oh shit, the power went out while I was gone, even though it's clearly back, which means every single thing in my fridge and freezer might have gotten room temperature and refrozen, and will give me food poisoning."
And it will be the only indication whatsoever not to eat it.
Anyway, just got back from the grocery store, but at least I don't have botulism.
I know this is a 'better safe than sorry' kind of scenario, but if you like me live in a place where power often goes off for a few minutes due to power grid failures in summer with all the A/C units going in the neighborhood, it's not going to help.
Put a glass full of water in the freezer. I use a shot glass to save space. Once the water is frozen, put a coin on top.
If when you're back the coin is under the ice, you know your shit has defrosted and should be thrown out.
