Why do people do this to each other?

So, one of my best friends says to me about another, "I'm done with her. I'm tired of her bullshit. I guess she accomplished what she set out to accomplish--she wanted to sever it, and she did."

She walked out, in tears, not knowing where she was going. I didn't stop her. I didn't know what to say. I guess there's nothing to say. At a certain point, you just cut yourself off from the trauma-inducing people in your life. Because you just can't live on the roller-coaster of their affections. I can't argue against that, as much as I feel like I ought to. Sometimes, there are no more second chances.

I feel angry. I feel a little teary, myself. But at the same time, it's all at one remove. There's just an empty space. Death does that, even the death of a friendship or a relationship.

It's been ten years. Most of us have grown up. Most of us.
