When friends are forced to be apart from each other for whatever length of time, it will be a difficult period for the two of them. They will be forced to go through their normal routines apart from each other. Each one may miss the qualities that the other contributed to the friendship. There is a saying that, "absence makes the heart grow fond". This may be an opportunity for each of them to realize how important each one is to the other's life.. They will miss each other, and long for the time when they can be together again.
