Story which makes me sad

I am sorry,
  but I tell stories.

I also try to have some kind of deeper meaning mixed into the words.

This time,
  I can't.

One of the two may stumble across these words,
  and she is the one I am sorry for.

Because she did nothing wrong.

The passing of years leads to strange changes,
  mainly in the mind are those most damaging.

Spent the time,
  out the door.

Leaving a trail of pain behind.

Knowing both,
  the results shock me.

So,
  I am sad,
   bitterly sad.
