This pedestrian tunnel we always use to walk through when I was a little kid. At the end of it, there is a utility box facing the exit and there is a graffiti of a grinning Snoopy wearing sunglasses. For some reason, they never paint or clean it up for many years. It always had been a greeting stable when we would walked by. Until one random day, it was finally painted over.
What goes up, will inevitably come back down. Whoever you have to step on when you go up, you will be at their mercy when you go down.
The truth is strictly what the ones in power perceives it to be.
Enjoy any good things, even the little and menial ones, as you will never know what impending distresses could descend upon you in a moment.
