One person-always silently watching you by your side There is someone-always inadvertently appearing in front of you There is a person-always taking care of you There is someone-always giving you joy when you are alone One person-always keeps you open when you are sad One person-always comforts you when you fail There is a person-always looking forward to your success One person-always laughing because you laugh and cry because you cry There is someone-always with you when you need someone most There is a man-he is not a lover but a friend Cherish the person in front of you, time can not go backwards, life can't regret it. Don't let your life grow old
