listen to those who love us and want to give us an advice when we have serious problems in our lives.
Parents have gained some life experiences and they know what to act in different situations. That's why
we should ask them for help first when they have problems. Therefore, there are moments when we avoid
them and don't want to follow them. With time passed, my brother as well as I have realized that our parents

time.
