"are you okay?"

Thing is. You walk around on this earth along with loads of other people, and the person next to you could be dying without you knowing. They could have cancer. Or maybe they could have Parkinson disease  But you don't know that, because it's not like every piece of information about a person is visibly scrabbled on a person. Or like when you can scan something with your phone, and you're directed to some website with more information. Real life is more complicated. Because we clamber to our secrets and hide them from the world, only for show to a few people. So when you sit down beside that sad-looking girl on the bus one day, it just might happen that she's been at the doctor and been told that she's got cancer in pancreas. And you won't even be entitled to ask her if she's okay, because that's not accepted behavior in our society. And you'll only end up looked upon as odd by other people. Because you're not supposed to ask strangers if they are okay, unless they are somewhat hurt. And the worst part is, that if you ask. They might just say "I'm fine". The probably most used lie in existence.
