This came to me last night. I got the idea while reading on a certain Tropes wiki that the phrase "Bar Mitzvah" was supposed to refer to the person, not the ceremony. So I pictured someone asking "Where's the bar mitzvah?" and being told "He's right over there," and the story just kind of unrolled from that point. I hope you enjoy it.
