That moment when you're nearly 22 but look like a child and people think your boyfriend is your dad

Oh that isn't normal?
No, but seriously the other day I went to the store with my boyfriend and not only did the cashier think I was going into my first year of high school, but he also told my boyfriend that he has a beautiful daughter (obviously talking about me). Le sigh. Will I ever hit puberty since I clearly skipped it...
