When I think of things that most of them have had in common…
The ability to make things worse, unnameable actions with no though to the potential long term impact.
The ability to trust, turned to the ability to believe the worst and still be proved right.
The ability to take a joyous occasion and turn it into a struggle with tears.
The ability to screw up idea of normal interaction.
The ability to offer support, but reject or blank any request (no matter how hard it was to ask, to share.)
Next time, if there is a next time, I need to learn to avoid them. They are too complicated and cause too much pain.
