Rabbi David A. Nelson likes to tell the story of two brothers who went to their rabbi to settle a longstanding feud. The rabbi got the two to reconcile their differences and shake hands. As they were about to leave, he asked each one to make a wish for the other in honor of the Jewish New Year.
The first brother turned to the other and said, "I wish you what you wish me."
At that, the second brother threw up his hands and said, "See, Rabbi, he's starting up again!"
