“Hey, easy man!! There is a turn ahead. Got it?”
Sorta thing this arrow notify everyone who passes by. He is standing there from years in rain, in nights, in fall, in summer, in winter, every time. We don’t give a damn because its lifeless, helpful, but lifeless!!!
Well, its matter of deep research, that, even if it was alive, someone would be actually bothered?
Some questions are better to be unanswered!!!
