6 things that could end you're friendship

for me, friendship is important. well because friend could back you up if you are in a difficult situation. but still, we are human. we made mistakes. and there are some mistakes that was taken seriously by our friends. ending in a relentless situation. here are 6 things that you and he/she is going to face this kind of ordeal. 
1) you made a mistake. a really big mistake until he/she couldn't forgive you
2) you and you're friend argue with each other. ended in a bad result
3) you're friend made a practical joke that up set you pretty badly
4) you spread lies about you're friend's ( well for fun maybe)
5) you meet a new friend that you're old friend do not like. then you need to choose which one the more better. and you choose this new friend.
6)  you're family argue with each other. which effect you're friendship pretty badly.
if you ended in those kinds of situation the best thing to do is apologize and never repeat the same mistake again. cherish you're friendship. cause you defiantly needed someone to rely on you're shoulder.
