My tool belt.
I was thinking of how I came to own a tool belt. When I was 21, I was hired to work on a siding crew and showed up with my tools in a bucket. All that sort of work I had done before was for the family business and we hauled our tools in buckets; it was all I knew.
My new foreman asked me where my tool belt was and I explained that I didn’t have one; he shook his head and, leaving us to work, went to check on another crew. At lunch he came to check up on our progress and threw a new tool belt my way saying something along the lines of, “put this on and stop embarrassing me.” It still hangs on a nail in my shop; ready to go.
