Recognition

It was half past eight in the morning. The Delhi Metro was standing still midway with the notifications about the delay going on. A man in his sixties was sitting in front of me. He was well dressed and had a glowing face, beaming with joy. Looking at his watch again and again, counting the number of stations left and then eagerly looking outside to check if the train started moving, he was getting very impatient. With every passing moment, he was getting a bit disappointed. Observing him for the last five minutes, I decided to strike a conversation with him.

"You seem to be in a hurry. Have you got an appointment with some doctor?", I enquired noticing the envelope of a hospital in his hand. "No. I have to take breakfast with my wife. She is admitted to a nearby hospital.", he replied.

"Ah, I see. How is she now? What happened to her?" This came entirely out of excitement.
"She is suffering from Alzheimer and has been admitted to the hospital for a long time. We always take our breakfast together", he replied with the same calmness.
I asked again,"Would she get angry with you if you got a bit late?"
"No." He took a long breath and continued. "Due to the disease she has completely forgotten about me and has not even identified me for the last five years."
I got a bit surprised. "You go to have breakfast with her daily even though she cannot recognize your presence!!!"
This time he smiled and replied,"She might not remember who I am but I know who She is."
