Jake collects stamps as a hobby, I asked him why he does so and how it became his hobby, in his reply he claimed he was doing it because he read about hobbies, most common being collection of stamps, so I got to try it out and it worked perfectly well, now he has a collection of thousands of stamps. People don’t send letters through regular mail and post office as they used to do in the olden days, that practice is slowly dying out, with the advent of electronic communication, fewer letters are sent physically compared to decades ago.
There’s a way in which people watch what others are doing, copy it and in turn soon becomes their hobby. This is a practice that’s slowly dying out yet there are people who are able to find interest in it, keep it alive, it’s an idea others thought it to be crazy, they proved it to be otherwise.
