Long time ago, everyone was responsible for the right upbringing of children. Wise children always listened and respected what elders told them.
When an elder advises you, be proud because they have something important to tell you. They advise you against any kind of bad habit which might ruin your academic future and your day to day life as a child.
Many children like listening to elders because they tell interesting folk stories that are also educative. One day after school when you have grown up, you will also be able to tell these stories to your children.
