Being a teenage girl has taught me

1. Consequently, if you’re not in possession of a tiny waist that could be encircled by probably a standard palm of some sweaty perverted swine, or a pair of “juicily” large breasts, you’ll never be as popular or as well liked as those who are more fortunately endowed. You also comfort yourself with the fact that it’s just a phase of horny teenage hood, but nope, it does not dissipate with the flow of time, shockingly.
2. No matter how many tears shed during graduation or promises made to keep in touch with each other, though in my case: none, you’ll only stay close with a selectively few number of trusted friends. Maybe once in a while you will encounter an exchange of many polite words to someone you once sat next to on the bus during a field trip, maybe you’ll even swap current phone numbers or succeed on making an exhilarating plan for next Saturday, but in the end, you’ll both end up mutually praying that the other has forgotten about it or the plan itself somehow just vanishes into thin air. And, as you will come to realise, this is probably for the best. You don’t really need to “do brunch” with that girl you once hung out with, you just think you do.
3. Never tell someone a secret that you have intended to remain secret. You heard me. Never! (with probably the exception of your best friend). Somehow, miraculously in some cases where both parties deny the responsibility, that secret will create its own wings and find its way to everyone you’ve ever met. Like The Pierces has cited many and many times: “Two can keep a secret if one of them is dead”.
4. If you’re engaged in any sexual contact with anyone, you’re a slut. No matter what the circumstances. If you’re not, you’re a prude, boring, a nerd, a freak, an unattractive monstrosity that no one desires, bla bla bla. And guess what, if you don’t reveal anything, they’ll just gonna assume anyway: “Oh her, that slut, she probably has already done it with 4973524 guys”. No matter what your level of sexuality is, comments will always be made and stories will always be fabricated.
5. One zit will ruin your week.
6. Your amount of procrastination time in total will at least double your productive periods studying for finals. 
7. If you ever order a salad or have greek yoghurt brought to school or one of those cereal 90 calories bar for snack, no doubt you will definitely be bombarded with judgemental ridicules. “You’re so skinny you don’t need to be on a diet” “Why torture yourself with these kinda stuff?” “Chill out girl, have a burger and fries”. That brings me the irony of society in number 8.
8. Society will expect you to “stop being so rigid and boring” in a way that “interesting” would mean you should eat an abnormally huge amount of unhealthy food, YET remain thin with perfectly perky breasts and butt. Cut me some fucking slack.
