My Memories of a VHS Video Camera

In the early 1980's when I was in primary school, my father bought a video camcorder for the first time. The news was really exciting for my family, especially for the children. Fortunately, my father didn’t hog the new camera. Even I, the youngest, was allowed to use it freely.

It was a huge, silver colored camera. It looked like an ENG camcorder. When shooting, not only did I have to put the camera part on my right shoulder but I also had to hang a VHS video deck over my left shoulder. They were really heavy. 

One day during shooting my elder brother was walking our dog and I fell into an U-shaped gutter. My right eye was watching the display in the viewfinder and on the other side my left eye was closed.
I was lucky that the camera and the deck didn't break but they were damaged.

I was afraid that I might be scolded by my father, but he didn't do that at all.
I learned that forgiveness is more beneficial than punishment.

One day, while I was shooting my elder brother walking our dog, I fell into an U-shaped gutter. My right eye had been watching the display in the viewfinder while the other was closed so I didn't see it coming.
It was lucky that the camera and the deck didn't break but they were scuffed up.

I was afraid that I might be scolded by my father, but he didn't do that at all.
I learned that forgiveness is a more effective teacher than punishment.
