The woman met a girl on her way home with her pet black girl. She only looked down at her phone but did not notice the open sewer manhole cover at her feet. At the critical moment, the woman's pet black girl hurriedly shouted at the girl. The girl who was stopped was startled and scolded the black girl ungratefully. When the woman saw this, she comforted the black girl not to care and praised her for doing the right thing and then stepped forward to close the manhole cover.
