I think the responsibility ends once it's out of your mouth, and the other begins when you hear someones words iykwim?

That said - if someone objects to your words you can review but if what you said was coming from a good place, there isn't much you can do, but if you look back and think -"hhmm, I was feeling pretty cranky when I said it might not have come out right, you can always do something about it.

AND if you hear some thing that upsets you, have a think if that person meant to upset you and if you don't think they did you can write it off to whatever reason. If you think they meant it badly, you can take it badly or think - oooo gotcha claws out today or say something directly in response (along the vein of "speak to others" yadda yadda).

But if you are going to hide under your bed for days over words said to you, I think it's time to investigate your own reactions

Did that make ANY sense???
