In seriousness though- if I had an anger issue I think it would depend strongly on your timing in telling me and who you are to me.
It would have to be at a time when I was not frustrated or spooled and was relaxed and undisturbed. It would have to be approached without confrontation and by someone who knew me that I respected.
I think that If approached like that the chances of having a person with anger issues blow up would be reduced.
Also if the person with the anger problem was a drinker they would have to be sober.
Great question- clever too.
