Not “a lot” of people look like me in the “Number 12 Looks Just Like You” sense, but I have a cousin who looks a lot like me, and is close to me in age. We were together pretty often as children, and people always asked us if we were twins.
We liked it. Sometimes we even dressed alike on purpose to encourage it.
As far as what’s “it” like? I don’t know if I can say. We went to the same school for a few years in elementary school, then again in high school, although she was a grade ahead (she’s eight months older: she was born in May, and I was born the following January). Our teachers and classmates could tell us apart, but other people in school called us the wrong name a lot. Somehow, I just knew when someone said her name, but meant me, and I answered. Most of the time, I didn’t correct people. Sometimes I’d turn around, and people would correct themselves, and apologize, and I’d say that it was OK. Sometimes even looking me full in the face, people couldn’t tell it was me and not her.
It didn’t mess with my sense of identity, or anything.
What did kind of mess with me was the fact that this same cousin has a younger sister who looks even more like me, although she is 15 years younger. I would take her places like the park, or the movies when she was little, and people would mistakes me for her mother. I never got used to that.
It made me really uncomfortable. I think a lot of it was the idea that people thought I’d had a baby at 15 (when I was still a virgin, and really, a little socially backward). Thing is, now when I look at pictures of myself at the time, I realize that I did look a few years older than I was, beginning about the age of 13. I was usually pegged for about three years older than I was, from about 13 to 20, but I didn’t believe it at the time.
When I was in college, there was someone in town who looked like me. I never met her, but her name was “Mary Anne.” I know this because of the number of people who called me that from behind, or a distance, then said “Sorry, I thought you were someone else.” I did meet her boyfriend once, who confirmed that we looked alike, but she was a little taller (
the whole world is taller than me), and he personally wouldn’t confuse us.
The “Mary Anne” thing was a little weird, but it was mostly because I never met her. I think if she’d been an actual person to me, it wouldn’t have been so strange. As it was, the first several times it happened, I wondered if I was sleepwalking, and introducing myself to people as Mary Anne. I watched Sally Field as Sybil at one point during college, and had this thought.
Another thing that kind of bugged me about the “Mary Anne” period was the fact that it seemed like a very gentile name. While I have not been mistaken for other specific people much, people have always been able to tell I’m Jewish-- except for the occasional person who thinks I’m Hispanic or Greek. I even had a woman once cross a busy street against traffic to accost me, and ask me about Jewish college life in town, because she’d just dropped her daughter off at school, and I was the first Jew she’d seen since she’d been in town.
People very frequently just ask me questions about local synagogues, or even speak Yiddish to me without saying something to first confirm that I’m Jewish. So, I look like a lot of people’s Socratic ideal of a Jew.
That’s been happening all my life, though; I don’t really have a “What’s it like?” answer, other than, I like it from other Jews, but it puts me on my guard when gentiles do it-- and yes, I can tell, not by how people look, but by what they say. I had my life threatened by someone in Bedford, Indiana, once, after he did no more than look at my face.
I hope that answer gets you a little closer to what you want.
