What's eating Vinaya N?

Apart from a report that a snail would say is going at snail's pace and segmentation faults that drop in unannounced, bug you the whole day and then disappear without giving you the satisfaction of having driven them away, it is this. Is it right to do unto others what they do to you? On one extreme, you can sink down to the level of the lowest human you meet, letting him get what he gives. And on the other, you can decide to take the high road, letting people take advantage of you in the process.
The answer, as usual, lies somewhere in between. In defining limits. A lower bound below which thou shalt not sink and an upper bound beyond which though shalt not be nice (My language affected by too much association with the people of a certain room in the department and re-watching I Dream Of Jeannie). And while the theory seems sound enough, the devil is in the (implementation) details!
