When a friend hurts us, we should write it down in the sand, here the winds of forgiveness get in charge of erasing it away, and when something great happens, we should engrave it in the stone of the moemory of the heart, where no wind can erase it.

老师：您好！请问这个句子中的 get 是与后面的 away 构成的短语，表示离开，是这么理解吗？还是说是 get+in charge of sth.这么理解的呀?谢谢。
