Hoarding bottles of wine meant to be consumed by guests (note the plural form) is tantamount to stealing, while overeating (as in gorging) is detrimental to one’s health.
Taking into account that caterers put leftover untouched foods to good use by giving them away to the needy (as in “hungry”) adds “taking from the poor” to the list of offenses committed by the overindulgent.
Your letter brings to mind the biblical verse in Devarim of “Vayishman Yeshurun va’yivat shomanta” – (Yeshurun grew fat and kicked), referring to a spiritual decline and arrogance borne of an abundance of physical comfort and prosperity.
Ironically, Pesach celebrates our spiritual emergence and is the time of year when we embark on a course of spiritual fortification to ready us for Mattan Torah. At the Seder table, whether at home or away, we invite all who are hungry to come and eat – Kol dichfin yasei v’yachol… in the hope that we (all of us here in golus today, rich and poor alike) will next year be free people — leshanah haba’ah bnei chorin.
Let us all help this become a reality.
