If you enjoyed responding (like I am doing now), then that's that. You got the worth of the time you spent. Of course, if one were _expecting_ more than that (e.g. others not being a jerk or even being nice), then its fulfillment is an added bonus. By not getting the bonus, should we be unhappy also about the salary that we already got? Or is this too idealistic an opinion? If the others' behavior _deeply_ affects us then we are too vulnerable, no?
