What sincerity have you been touched by?

I was moved by the kindness of strangers more than once. At that time, I was a child who had just entered the city. Besides a heavy backpack, I also have an overweight suitcase. I dragged my suitcase up the stairs. That staircase is really super high. I struggled to lift the box layer by layer, almost to the top. My hand slipped and the whole box rolled down. Fortunately, I didn't hit anyone, but the tears really stayed. After all, I was a child, and I was in distress in a big city for the first time. Just when I was at a loss, the man halfway up the stairs turned and ran down, easily helped me with my suitcase and mentioned it to the top floor. I can't say all the excitement, but I keep saying thank you. I didn't have the contact information of that brother until the end. That was the first time I felt the human touch from strangers. It may be a casual thing for him, but it is a kindness that I will never forget.
