People who are always there for you no matter what are like gold that you must continue to treasure, it is not good to cut off such relationships because you had a slight argument.
Life is already hard, don't make it harder by ending relationships because of some minor arguments. Real friends that just love you for who you are should not be taken for granted, because they are hard to find. Even money cannot buy you true friends.
If you keep burning every bridges that comes your way, you might find it hard to cross a big river when the time comes. If all you do is cut off friends because you had disagreement, a time will come when you will need them to solve big problems, and they will not be available for you. It is easy to burn bridges, but it requires a hard work to rebuild them back, don't cut off real friends.
You should understand that in this world good people are hand to find, those who would care about you are rare. Don't think you can just go out and find someone who would take and care about your shits.
Be mature to know that in every relationship there must be some sort of disagreement, opinions would differ, but that does not mean the relationship is no longer worth it. You should be wise enough to understand that people are different, so is also their thinking, that does not mean you cannot work with them to achieve something great.
Understand the difference in perspective with people you are in relationship with, and come to respect them instead cutting them off entirely because of that. Don't lose a valuable relationships because of just a misunderstanding that won't remove an inch from your life, be wise, be mature enough to over look things that don't matter.
Cherish those who care about you, like gold good people who care about you are hard to find.
