恳求高人翻译下面文章
Life is filled with challenges. As we get older we come to realize that those challenges to the very things than shape us and make us who we are ,it is the same with the challenges that come with friendship .
When we are fared with a challenge, we usually have two choices . we can try to beat it off, or we can decide that the thing presenting the challenge isn’t worth the trouble and call it quits. Although there are certainly times when calling it quits it the right thing to do, in most cases all that is needed is commitment and communicable.
When we are communed to something, it means that no matter how painful or how uncomfortable something is, we will always choose to face it trough instead of running away from it. Communication is making a space for discussion and talking about how you feel as opposed to just saying what the other person did wrong. If you can say to a friend, “I got my feelings hurt.” Rather than “You hurt my feelings,” you are going to be able solve the problem much faster.
In dealing with many challenges that friendship will bring to you, try to see them for what they are: small hurdles you need to jump or get through on your way through life. Nothing is so big that it is impossible to get over, and hurt only serves to make us stronger. It s all part of growing up, it happens to everyone, and some day you will look back on all of this and say, “Hard as it was, it make me who I am today. And that a good thing.”
