All is not lost. Being human beings, we just never stick with the same thing. At one time you may have ended hurting your friend or best friend. Even if you have done and wanted the clock to reverse the situation then we are here. Just follow or acknowledge these things and it will be on the right track.
The first thing you may realize that you were wrong and so he may think you are wrong. In this situation, you need to calm down and just have some space to think. You need to think from the beginning that how it started and why for what reason? You can also need to think from a third perspective.
In every matter, without regret, you need to initiate conversation. Either it’s your fault or his/her, you need to set your ego aside. A face-off conversation is always better and clears most of the things. Never initiate with email, text, or with someone of a middleman. Here, you need to be open and honest. If you try to sweep and start with jokes; it may go worse.
“Friendship is the hardest thing in the world to explain. It’s not something you learn in school. But if you haven’t learned the meaning of friendship, you haven’t learned anything.” – Muhammad Ali
It’s best of all, every time it works as well. You need to listen to your friend by being open to his/her feelings and thoughts. By listening also you will make sure that it’s important as much as they do.
“If you go looking for a friend, you’re going to find they’re very scarce. If you go out to be a friend, you’ll find them everywhere.”– Zig Ziglar
It’s not about repeating the mistake but not to repeat. It’s better to stay away from the issues that offend him/her a lot. Believe me that you could be forgiven once or twice but may not happen always.
Friendship is one of the most valuable treasure and you need to preserve it. They teach you and you teach them that no school or family can teach. Also, it difficult to find true friends so don’t turn them away with the small understandable issue.
