I was reading an interesting book called metal boxes and the main character had never lived outside a ship of one form or the other in that. He'd never seen the skies and finds it very scary when he experiences the open. It was a science fiction(a well written one) but there is a grain of truth in it.
We're all stuck in metal boxes of one type or another. These are the sanitized version of the world we create for ourselves, because let's face it, the world is a scary place. When we peek out of these boxes, we find things to embrace at times. But then, if we're judged by those we least expect to, we want to crawl right back in and never come out. I guess, it's all about a risk, reward, evolution thing. If you're ready to look beyond your metal boxes(there's not always a necessity) and try to expand your reach, you might be rewarded with an evolution, but not always. You might be beaten black and blue(metaphorically of course) and left to fend for yourself. What you choose to do at every point in time is completely up to you.
I just hope I don't lose the child like wonder when I look at the world most of the time. My box looks so comforting and cozy. I want to crawl right back in at times.
