Nature.

The thick glass wall felt invasive as I looked through it, watching the vehicles fly by, distorting the clouds. I lost the notion of space, time and self, forgot about my body under the spell of boredom (as overstimulated people call it) and drown into a trance that made me look like my cat, that contemplative feline look that pierces far away but considering everything along the way, thinking about nothing and everything at the same time; bored, annoyed, pleased, focused, devastated, calm... Nobody could know, not even me. 

The faint sound of a door and some calculated steps made me return. The sentence I heard was the most predictable ever in the history of humanity, and yet I felt a profound sadness filling up my body, culminating into the idea that the whole past 5,000 years were in vain: "We're going up another level". How many levels were there? We haven't seen any soil or rain for some decades now. "Don't worry, we will adjust to a new height, as we always had". That wasn't the question in my mind...

If only I could forget my nature, our nature, maybe, just maybe, I wouldn't miss it.
