Go to your local Young Israel or shul that builds a sukkah for the shul kiddush. Their sukkahs are very big, and built with the understanding that people who don’t have access to a sukkah, can use theirs.
Have a little pushcart or stroller for food (as long as you use an eruv) and have fun. Or, if you are in a small, intimate, kiruv community join their communal events, or get invited out.
This is beauty of jeff Seidel and the Machlis family in Israel. They make everyone feel at ease and let them enjoy ‘winging it’. Be flexible and have fun. My wife is laughing how mellow I am getting in my old age!! But, that’s how you stay young.
