One day my sister did not come home from college at her regular time. My mother was very annoyed with her.
She was just saying that she would scold her soundly on her return, when the door bell rang. Presuming it was my sister, my mother started yelling at her without opening the door.
I ran to the window to see my sister’s reaction to being shouted at. What I saw amazed me! Standing on our door-step, pale with shock, was our daily milk vendor who had come to deliver some milk.
