In primary school I was told I'd have to wear a ponytail if I grew my hair out because I'm AMAB, and I think it's the single biggest factor in delaying my transition. I could have figured this stuff out when I was 10 if I'd been allowed to experiment at my own pace.
My all-boys high school had a rule that hair couldn't be long enough to touch your shirt collar. Being allowed a ponytail would have been an upgrade if I hadn't just stopped following the rules.
American only allow eat what on McDonald menu. And at the Bloomfield Barber Shop in Bloomfield, NJ you can only get these haircuts, any deviation results in termination by Dark Brandon.
