Are Jerusalemites in general aloof and unfriendly, particularly the Orthodox? Some think so, fairly or unfairly. There even exists a joke about this alleged aloofness: Thank G-d for the monthly Kiddush Levanah ceremony. It forces Jerusalemites to say shalom aleichem to a stranger at least once a month. (For those unfamiliar with this rite: During the prayers sanctifying the new moon — Kiddush Levanah — there is a requirement to say “shalom aleichem” to three participants.)
