Supplies were most important, I decided, and took the left path. I walked for about an hour and a half before I found a pile of rubble which used to be a corner shop. Underneath a broken chiller cabinet I found undamaged, several bottles of water, a cheese and pickle sandwhich still in its packaging, and six packets of cheese and onion crisps. Just my luck there were no salt and vinegar crisps left when the world ended.
So. I had supplies. What next?
