When I opened the webpage as usual and saw the sentence "Sometimes people make mistakes or go into dead ends because they don't have friends around them or they don't ask for help from friends, they go into dead ends and are immersed in their own world", my heart was hit hard. Everyone's life is full of strange things, but there are always many dead ends waiting for us. If you are unfortunate enough to have only one tendon, then you will find that your world is slowly dimming. When the sun no longer shines in, or cannot shine in, the feeling of being at a loss will defeat us.
