See this the problem with you children. You think you're so intelligent, that you have such a firm grasp on the world around you. 10 years ago, I thought the same thing. Then I became an adult. I had bills to pay, a life to live, responsibilities that held me. I became an adult. And you know what I learned? That being a kid, having everything taken care of and only having to worry about if I had enough money to go watch that movie, was nothing.
Grow up, gain some financial independence, and then tell me how it feels to have little 16 year old shits telling you how "hard" their life is and how they "know" what it's like to be an adult makes you feel. It'll make you laugh. Because you teenagers don't know jack shit about being an actual adult - a contributing member of society.
