toilet paper or canned food?
If you don't eat for a week, there's no need for toilet paper.

Serously, the worst is having no water. Our water is linked to electricity. When there's no electricity for more than a day, water will run out. And then people from other phases come to our street for the water pump.
Ack, every phase has its own water pump, but ours is the only one regularly maintained... That is... Before last year. Oh no!!
