I have always been mistaken for being years or even a decade younger than I am.
In high school I was told multiple times I looked 11, once while checking out at the grocery store, by myself, with my car keys in my hand
at university when taking classes at the campus gym I was asked if high schoolers were allowed to join the gym.
As a 25 year old grad student I would get stopped at the entrance of stores during the lunch break of the local high school and asked to either leave my bag or wait (they had limits on how many high schoolers were allowed in at lunch)
Until my 20s I was painfully skinny as well, which added to my childlike look (I weighed 85lbs and was 5’3 according to my first driver’s license - don’t worry, definitely do not have that problem anymore)
But even when I started my new job a coworker remarked that I looked 19 (I was 33)
I believe I still look quite a bit younger than my actual age to people, though I am now thirty-mumble mumble.
I’ve got a round face and freckles and a sort of ‘button nose’ so I guess that is probably what makes me look young.
Also never really wear makeup, so that could contribute?
but now that I am an oldish mom, and not mistaken for a child anymore, I don’t mind so much.
(Even though it never bothered me too much to be mistaken for younger, everyone told me I would appreciate it when I was older and I hated that, but unfortunately it ended up being true…
