Dearest Rav David,
On behalf of all of the students and staff at EVO, I want to thank you for making our trip to Poland as meaningful as you promised it would be. From now on, I think that we can all agree that you cannot take a trip to Poland without both Yankel AND Rav David.
Words cannot describe how thankful we are to have had the opportunity to learn with you this past week. You never once lost your patience with us, answered each of our questions (relevant or not), and spoke continuous words of wisdom throughout the journey. And while we may not be there next week, we'll continue to take the lessons we've learned with us always, and hopefully be able to apply them not only to our lives, but to our children's as well.
Thank you for everything you did to make the trip what it was. We know you put your heart into it.
See you again at all of our weddings (B'ezrat Hashem), with the Love of the Torah."
