one's decision to cut off a person from one's life is like a song played at one's best with only two strings left on a double six and a metal slide to hide it. just like this:
- good for one, good for the other
- good for one, irrelevant for the other
- good for one, bad for the other
- irrelevant for one, good for the other
- irrelevant for one, irrelevant for the other
- irrelevant for one, bad for the other
- bad for one, good for the other
- bad for one, irrelevant for the other
- bad for one, bad for the other
i will let you consider the short term and the long term variations and probabilities, also the particularities and different cases. everybody has them.
