Back in my teens, when I was still working as an apprentice electrician. I was given the task of fitting up some office ceiling lights in a building that was being completely renovated. There were carpenters, decorators and builders all working on different parts throughout the building. Everything was pretty much coming to an end and being finished off. These were the things I was fitting for reference:
I had several large rooms to do. A lot of climbing up and down a step ladder, grabbing another fitting each time and slowly making my way from ceiling tile to ceiling tile. Anyway, while fitting one of the lights, it suddenly came loose and smacked me on the head as I was descending the step ladder. Didn't really hurt, but when I gathered my bearings, I noticed there was one of the painter and decorators looking at me through the office window laughing his head off.
To add to it all. He was deaf and communicated through sign language. So during lunch I had the joy of watching him sign language to the other workers what he saw. With his colleague translating for everyone. That made me feel pretty stupid.
