A vivid childhood memory

There was once when I was 5 years old and my parents decided to bring me to a gymnastics club at Raffles institution. The coaches there were very strict and would either scold or punish me if I talked while we were training. The punishment was very harsh and tiring. I was afraid of him punishing me so I kept my mouth shut the whole time and did not dare to talk. This caused me to learn to be more obedient and less mischievous. It also taught me to keep quite during class and listen to the teacher.
