@mommunism:
I have real-life experience.
My acquaintances (in the same district) are now still grief in sorrow for not being strict with their son until they heard the phone call from the hospital to come and take their son's corpse back.
Traffic accident, he didn't wear a helmet.
Because he was their only son, they spoiled him rotten. They always gave him whatever he likes to encourage him to study. He was rather smart but was also lazy.
They often told him to wear a helmet but he was like "No need, there are a lot of people don't wear a helmet while riding"
Meanwhile, back when I was a child, I chase a ball and was about to get hit by a bike.
My mom slapped me real hard in the face, it was really hurt.
But then she sat down and hugged me really tight while crying "Why didn't you be careful? What if you got git and died, how could I live? Thank god you are alive!"
I was even more hurt than when I got slapped.
From that lesson, I always remember to be careful of vehicles whenever I go out.
But I doubt if I could learn that lesson if my parent gave me candies and told me to be careful.
The only bad thing is that I may have become worried too much that people often call me a worry-wart.
