An old advice
Today, during my lunch walk at the office, I suddenly recalled something my father used to constantly remind me many years ago.
As a kid, I had this habit of walking with my hands inside my jean's pockets. Each time my father saw that, he asked me to take them out. Then he used to said: “if you suddenly fall down, you won't be able to use your hands to avoid hitting the floor”, or something along those lines.
I don't know why I walked like that. Perhaps, somehow, it has a calming effect on me. Sure, he had a point, but his constant reminders were slightly annoying at the time.
Over the years, however, I have discovered different layers of meaning in his words.
