Cantor Marci Vitkus; Writing a Legacy Letter. A legacy letter, sometimes called forever letter or ethical will, is a kind of correspondence that one might share with those whom you love. The forever letter is a heartfelt note written to the people who are most important to us with the hope that even if the letter isn’t kept forever, the wisdom and love that we share will be. Come prepared to begin writing notes to create your own legacy letter. This is an opportunity to reflect on your life and offer what matters most to you and share it with loved ones.
