We were paying for what we needed from the convenience store together. I looked at the receipt in my hand which consisted of a couple of pages and wondered what happened to the things that I had bought. All of the stuff we got was in a pile on the floor as someone announced the items we had bought one by one. Most of them were books of practical jokes or about cell regeneration and damage. “Now what does all of that mean?” someone said as they laid on the sofa after reading out one of the titles.
