Why did the poet suppress her pain in the presence of her mother at the airport?

 

Ans. While travelling with her mother in her car to Cochin airport, she noticed her mother's face very closely. It looked pale like the face of a dead person. She was shocked and afraid that her mother would not live for more time. But she suppressed her worry. She does not want to show her sad face to her mother. So, she gave a broad smile to her mother.
