We all have feelings and get angry,upset.sometimes some even want to intentionally hurt the other one because of their pain or to "teach the lesson".
One thing we have to realize ,words have immense power,they can destroy carefully built castle of trust in the matter of minutes, once out you can't bring them back,but only hope o correct the damage in time.I learned,that I have to be extremely careful in expressing my emotions ,in order to avoid creating further destruction(unless you really want to severe relationship with that person)
Nobody don't get positive reaction and effect from negative comment

Good luck
