He came up to me at my tefillin cart and said, "Seven years ago you saw me smoking and you Yelled at me to quit. Actually, you yelled at me a few times because I didn't listen at first, but finally I listened, and I quit smoking. I haven't smoked in seven years. Not only that, but like you said, now that I quit I can't stand the smell of them.
"Then you yelled at me to get rid of my non-Jewish girlfriend, and I listened to you. And, thank G-d, I married a wonderful Jewish girl.
"And now, just today, I received my rabbinical ordination, so I am a rabbi. Thank you very much for changing my life."
Smart guy…he listened to good advice and look where it took him.
