Me and my magnet and my dead friend

When I was a child, I used to tie a magnet to the back of my pants and pull it out all day because I had nothing else to do. A magnet can attract a lot of nails, screws and beer bottle caps on the road, which made me very happy. Ming, like me, had nothing to do, and we often play poking lottery together. I thought this would last forever. However, after a heavy rain, Ming passed away unexpectedly, and that’s where my childhood ended.
