Yesterday I went to a construction site to deliver something to a relative. I picked up the welding machine and tried to ignite it. I found that I hadn't touched the welding gun for several years and my hands started to shake. The weld was already very rough. I bent over and fixed it for about 10 minutes. My skills have declined and my ability to make a living has been wasted. Damn it, I have to be more stable in the future.
