Sorry if i caused offence. Wasn't directed specifically at you ecomouse.
Rather that the reasons other people would have for writing that letter are so markedly different from those of the OP.
Which seems to be about getting her ex and OW beaten up, through disingenuous letter-writing, and using this other chap as a tool, acting at a distance. Albeit a tool gifted with some degree of free will.
So it's about pulling a lever, which may cause a machine to perform action A, or B. The fact that there is a degree of undecidability, and the fact that it is the machine that will cause the action offers a bit of a get-out for the lever-puller. You can even focus on the lever-pulling, rather than the actions, A and B.
But, if you are pulling the lever, hoping that action A (some other person will beat up your ex and OW) will take place, that is just what you are doing. And it sucks. Imo. Though not a court in the country would convict you. And if it goes very pear-shaped, you can always tell yourself you had no way of really knowing if that would happen.
I suppose I am just very uncomfortable because there seems to be more of this "I'm going to batter the OW" thing about of late. And this just struck me as one of those.
And I'm probably wrong.
And I apologise to the OP if I am.
