Instead of running away from the obstacles or problems, why don't we try our best to get over them? Human nowadays become more and more scared of the problems they will confront with. They only expect good things to happen on them and afraid to step into the problems and solve them.
Friendship is not something easy to gain but it's so obvious can be destroyed in just a short moment. However, there's no enemy and friend forever. You best friend can be your greatest enemy in the next minute.
If that really happen, don't run from it. Do your best to overcome that problem because it might be you who cause this change. Escape is not a good idea. Figure out why happen this kind of thing and do your best to solve it.
We are not only gaining age but also experience when time pass. Use the time wisely and also don't ruin the friendship. You need friend as much as you need your family.
