On Friday we visited Mount Carmel, a home for the elderly, and we did a model sedar for them. Many of the people there do not speak English, causing a language barrier. It is important to do this for them year after year, regardless of the language barrier, because it fulfills the mitzvah of Hiddur P’nai Zaken. This means we are respecting the elderly.
The other reason we do this is because some of the residents at Mount Carmel may have forgotten how to conduct a sedar over the years. This was important because we helped them be able to fulfill mitzvahs on, or close to, the holiday.
