I am also sending the printed essay along with this. Here's an excerpt: In the extreme cold, during a break in the construction work, I head to the vending machine and buy a piping hot can of coffee (short can). Warming my numb hands with the can, I drink it down with my colleagues, exhaling white breath. I'm sure I'm not the only one who thinks of canned coffee when they hear "construction site." However, I've lived a life almost completely unrelated to construction sites. I've only had the image of "construction site = canned coffee" imprinted on me through TV commercials and advertisements, and I didn't know how the workers actually drank their beverages on site. If I think about it rationally, coffee, which contains caffeine that has a diuretic effect, could hinder work on site. I even doubted that canned coffee wasn't actually consumed that much and was just a false image created by advertising. However, recently, I had the opportunity to be present at a construction site for a long time as the client. Surprisingly, the scene that unfolded there was just as I had imagined. Every break, the workers were drinking canned coffee. And they were doing it in a way that would never be depicted in a TV commercial. At that site, several companies were working in shifts, including the general contractor, electrical contractors, scaffolding contractors, and metalworking contractors. Not everyone was always present, but there were often four or five of us on site at the same time, including myself. ------------------ (Middle part omitted) ------------------ As I received and gave canned coffee myself, I began to see this commonplace item as something special. While it's a size that fits in one hand, it slightly crosses the boundaries between people and fosters collaboration. I even ended up taking the empty cans home and displaying them, as if they were something special.
