As a 5'1.5" female, I don't give a fuck what height people are. I do think they're lame if they're so insecure as to lie about it, though. I also think tall women who refuse to wear heels that they like because it will make them "too tall" are insecure. I think girls who refuse to date guys below a certain height are sexist and silly.
I think some people tend to treat me like a little kid (although they know I'm a teenager) just based on my height.
I'm 28 and get treated like a teenager. Welcome to the rest of your life. I hold out hope that I might be respected as an adult by the time I'm 50.
