describe the meeting of hawking and the author?

The author met Stephen Hawking during a walking tour through Cambridge. He was very excited to meet him even though it was just for half-an- hour. Professor Hawking who was confined to a wheelchair like the author himself because of a form of paralysis, could speak only by punching buttons on a computer, which spoke for him in a machine-like voice. The author felt guilty every time he spoke to him as it forced him to respond with much difficulty. From time to time Hawking had to shut his eyes in frustrated exhaustion as he struggled to find the words on his computer by the movement of his long, pale fingers. The author asked many questions to him, to which he replied and when Hawking smiled his oneway smile, the author knew that he was looking at one of the most beautiful men in the world. The author told Hawking how he had been an inspiration for him and many others. When the author asked him if there is any advice that he can give to disabled people, he said that they should concentrate on what they are good at rather than wasting time on difficult things. After the half-an-hour meeting was over, the author stood up to leave but Hawking asked him to stay for some more time and offered him to have some tea. He also offered to show his garden which was as big as a park. The author felt utmost admiration for Hawking after meeting him as to him he was like an embodiment of his own bravest self.
