Ivcap, you have been using words like old hag, kuku, ###### to describe the aunty which I think is uncalled for. True, maybe she did quote you the wrong price for the wrong fish but why are you so worked up over it that you can't get over the incident? Over a fish?
Your belittling only succeeds in lowering yourself in the eyes of others. Personally, I feel you gone a bit too far with the name calling.
