Many university students have never said “Thank You” to their parents. Their parents have done all they could to bring them up in the past score of years, but have never been rewarded with gratitude.The subjects claim such reasons as follows. First and foremost, a quarter of interviewed students regard it as parentsu2019 duty to support them spiritually and financially. And it is no necessary to express appreciation to their parents. However, the majority of youngsters is aware of their parentsu2019 love but is not accustomed to saying “Thank you”. Some even find a generation gap between themselves and their parents, thus feeling reluctant to express their affection for their parents.In my opinion, extending thankfulness to our parents is a way of respecting them and their love. We should express our feelings directly and bravely, but whatu2019s more important is, we should do all that we can to reward them.Selfishness is a bit prevailing in university dormitories. Some never care about othersu2019 needs or offer help to their roommates. Some even interrupt othersu2019 normal daily life by speaking loudly, turning on the loudspeakers and telephoning at midnight.As only children in their families, most of them are the apples of their parentsu2019 eye. They have been spoiled and are used to being satisfied. Therefore, they hardly pay any attention to othersu2019 feelings initiatively. What they care about is how to meet their own demands and how to get what they need from others. Moreover, selfish people do not know mutual respect and mutual help are keys to harmonies dormitory life.Selfishness erodes youngstersu2019 mind and many well undermine their all-round development. Only when we become respectful and helpful to each other, can we create a healthy atmosphere for dormitory life.
