I rushed to the sandbox and saw: my son was crying, sobbing so hard that he was choking on his tears, and next to him stood an unfamiliar woman. She was hastily saying something to him, but when she noticed me, she abruptly turned around and walked away quickly.

For a moment I froze, not knowing whether to run after the stranger or calm my child first. My son was screaming so loudly and breathing so heavily that I decided to hug him tightly and hold him close.
