"I'm being held hostage by a serial killer who's getting ready to kill me any minute, and I was only just now able to get to my phone to get this text out without him noticing. What should I do?"
Ok, well, I probably can't convince you to stay away from the Internet, so I'm just gonna warn you, be very careful out here. Like, I cannot stress enough how careful you have to be on the Internet. Do not trust anyone, don't let it take time away from your social life, and stay away from any person that tries to bully you (don't fight back, just stay away), stay away from anyone asking for money for ANY reason, even if and if you ever see porn, GET OUT immediately.
Sorry if I sound like a bossy adult, just know that you'll appreciate the advice when you're older.
