At the airport, the poet feels worried about her ageing mother. She is anxious that soon she is going to lose her mother; her final separation (by death) from her mother scared her. To hide her fear and anxiety, she smiles and calls out ‘see you soon Amma’. A cheerful farewell allows her not to show her pain.
The poetess’ feelings at the airport were of fear because she was afraid that her mother was going to die because she was looking very weak and she was not sure whether she would be able to meet her mother again. She hides her fear by smiling and assures her mother that they would meet again.
