concequence losing a friend

all people sometimes have troubles with friendship. because of this trouble these friend's fight each other and their friendship was no more. all people must have regret later on. before both of you and you're friend become enemy, you must APOLOGIZE. say sorry to them or who knows what will happen later on. making enemy is even more easier then friend, but they will have consequences. I've already seen a lot of good friend become enemies. say sorry for you is simple. but what about you're heart? is it ready to forgive? forgive what you're friend did to you? or not? you're choice.
