Rabbi Bun said: "so that you may remember the day of your going out from the land of Egypt all the days of your life" (Deuteronomy 16:3) means the days on which you are occupied with the living, and not the days on which you are occupied with the dead.
All the Days of Your Life Means Days With the Living
Yalkut Shimoni on Torah 102:14
אָמַר רַבִּי בּוּן (דברים טז, ג) "לְמַעַן תִּזְכֹּר אֶת יוֹם צֵאתְךָ מֵאֶרֶץ מִצְרַיִם כָּל יְמֵי חַיֶּיךָ", יָמִים שֶׁאַתָּה עוֹסֵק בָּהֶם בַּחַיִּים וְלֹא יָמִים שֶׁאַתָּה עוֹסֵק בָּהֶם בַּמֵּתִים.
