For example, don’t rub it in your sister’s face whenever you get a good grade. Your sister may be self conscious about getting lower grades than you, so don’t make her feel bad. Celebrate your sister accomplishments instead of belittling them. If your sister had a great volleyball game, congratulate her instead of being jealous. [3] X Research source
