A person who walks alone is not someone to be underestimated; either they are born with a wolf-like nature, or life has worn them down to the bone. He has been stabbed in the chest with the deepest wound and has crawled out of the abyss bit by bit. In a world that is cold and indifferent, he has long chewed and swallowed the bitterness, forging a resilience deep within. Living is not about shouting it out; it's about gritting your teeth and crawling out of the mud. You haven't walked through the thorns he has, nor tasted the shards of glass he has swallowed, so what right do you have to advise him to be kind? Such a person has long become their own armor, filled with pride, a rich inner life, and walks alone as if among the crowd. With mountains and seas in his heart, why would he need to join the masses?
