 :Anyway, I would like to make Peace with you. 
 :Is that possible? And let's skip the Rabbi above, he will not help, just telling us that we are both right. 
 :I'm even willing to go to a Polish priest (maybe he will do a better job than that Jewish Rabbi above), if that helps. 
 :But maybe - just maybe - that Rabbi was right: I am right, and you are right. Or am I crazy to say that?  
 :Unfortunately, the great Polish Pope is no longer with us. Peace? & Cheers! Yours truly,
