This comment was posted by sandwich_witch in the "off my chest" section on reddit. It's exactly what it's like to be a young girl:
"I am not excusing rudeness, but here it is from the perspective of a hot young girl:
You go through your childhood without any sexual overtures being made at you (hopefully). You wear jeans with reinforced knees and hair clips. The only thing anyone expects of your looks is to wipe the ketchup off your face once in a while and maybe bathe sometimes. Life is good.
Then you hit puberty and start to sprout lumps and bumps and you have no idea what to do with any of them, but everyone is noticing and commenting and making you very very aware of them. Your clothes stop fitting, your friends are putting black goop on their eyelashes and that awful fruity lip gloss that tastes like microwaved jelly beans, and worst of all, boys are looking at you. Not just the old "ew, a girl, cooties!" looking. They are looking at your chest and your behind and everything in between. The rude ones will comment and the even ruder ones will get grabby. You feel scared and inexplicably dirty.
As you grow, those boys will get bolder and pushier. And not just boys-- men, years or even decades older than you. They will look you up and down, analyzing your body like you are a shelf in the supermarket. They yell at you from cars and construction sites and sidewalks, leer at you in class, even insult you online (TITS or GTFO anyone?). You may have your first boyfriend. If you're lucky, he won't pressure you into sex before you're ready. If you're lucky, your friends won't find out and call you a slut or a whore or God knows what else.
You keep growing. You learn caution and who to ignore. You may become a little paranoid-- that nice man behind the checkout counter, is he making small talk or flirting? Did he just look at your chest again? You remember the time you were nice to that boy in class who invited you to a party and then tried to reach up your dress. You have the sinking feeling that the way you look makes you public property, diminishing anything else you might have to offer.
And yes, some girls will get rude, or touchy, or jump to conclusions, because they have been through this so many times it has become a wall, a suit of armor, to protect themselves. Even if they have nothing to fear, they don't know you, and fear is one of the first things women are taught to carry with them. It isn't you-- it's what led up to it. Again, I don't excuse it, but do try to understand."
