The meaning of a friendship?

Sometimes, I wonder about the meaning of a friendship. Do friends just fall apart because carelessness or forgetfulness of one? Do friends get angry at each other and keep the grudge? A superficial friend, maybe. But a true friend tries to accept and understand one’s faults. Perhaps hoping that the friend would graciously accept an apology would be a little too much to ask, but at least, the friend would have listened to the explanation given. And after a session of shouting at each other, all would be blown over and thus, friends again.

I really don’t get this silent treatment and the cold shoulder. Probably, the friend thought I changed over the past month, but all I can say is, I’m still me. As of now, I managed to keep all my promises, until that one time, when I had to sign out of an outing due to a selfish reason (probably). Am I not allowed back out of any outings? Would I seem unfaithful in the friendship just because I can’t make it to an outing planned ahead?

Sometimes, I wonder if I’m the one at fault. But at other times, I thought, why should I even care about what others think. I’m probably a little of a door mat, but that doesn’t mean I don’t have opinions of my own.

What’s the value of a friendship if it can be broken just by a sheer episode of forgetfulness?
