Imagine that every day of your life, someone is stalking you. Around every corner, someone is waiting to ambush you and take your picture. You can't pick your nose, scratch your balls, steal a kiss or pick a scab without someone snapping your picture. They run alongside you while you're trying to jog and meditate as you run. Sometimes, in their zeal, they actually bump/push/run into you.
They get in your way when you try to drive. They follow your car, sometimes at high speeds, sometimes pulling up beside you and blinding you with their flashes. In those moments, you remember a certain Princess and her untimely death as she fled just such a group of stalkers. You wonder if maybe this time it will be you.
They stalk whoever you are trying to date, and any intimate moment spent in a romantic restaurant can be ruined by a rude and pushy camera man. They follow you around on your vacation in a foreign country, where you've gone to perhaps escape the attention you live with 24/7 back home.
They go through your trash. They follow you into the bathroom. They follow your family. They yell things at you or call you names to try to get you angry so they can get a picture of you acting out. Any mistake or human moment you have where you appear less than perfect will be dissected, replayed, and reported on, with pictures looming forever on the internet, where people who don't even know you will discuss how big an asshole you are for your alleged actions. From the moment you walk out the door, you are a target.
Who wouldn't go just a little mad under such scrutiny?
