People come into your life for a reason, a season, or a lifetime. When you figure out which one it is, you will know exactly to do for each person. When people are in your life for a reason, it is to meet a need you have expressed. They have come to assist you through a difficulty, to you with guidance and support, to aid you physically, emotionally, or spiritually. They are there for the reason you need them to be. Then, any wrong doing on your part or at any inconvenient time, they will say or do something to bring the relationship to an end. Sometimes they die, sometimes they away, and sometimesthey act up and force you to take a stand. What you must is that your need has been met, and your desire fulfilled. When their work is done, it is time to on. When people come into your life for a season, it is because your turn has come to share, grow and learn. They bring you a(n) of peace, or make you laugh. They may teach you something you have done. They usually give you an unbelievable amount of joy. Believe it! It is real! But, only for a season. Lifetime relationships teach you lifetime lessons: those things you must build upon in order to have a emotional (情感的) foundation. Your job is to accept the lessons, love the person, and put what you have to use in all other relationships and areas of your life. It is said that love is sacred but friendship is sensible. In a word, thank you for being part of my life, you were here for a reason, a season or a lifetime.
