Generation gap causes conflicts between adults and teenagers when there are lots of differences between parents, grandparents and children in lifestyle, hobbies and table manners. While parents want their children to dress discreetly, children prefer fashionable clothes. Another typical difference is in the hobbies. Children like upbeat music such as pop music, rock, … However, grandparents thinks the types of music are too noisy, they like folk music. Some children complain that they feel sad when their parents are always comparing them to the girl or boy living next door. For example, when receiving an academic achievement, their parent always find the result of the girl or boy living next door. If the children’s result is lower, parents will complain and underestimate their effort. To narrow the generation gap, they should have mutual understanding, help each other and share interest.
