Dear Nicki,
I am turning twenty three this coming Friday. I have arranged a small party on Sunday at the Black ‘n’ White restaurant that is close to your place at 17.00 hours. I wish your presence on the occasion. The party is an informal one and is a theme based one. So, you are requested to dress based on Hawaiian theme. The party would be a great time to catch up with all our old friends and have fun just like old times. There is a dance party in the beginning and after that there is arrangement of snacks and dinner. I will also mail you the details of the party. I will look forward to meet you at the party and would appreciate if you could confirm your presence well before time so that I can make the arrangements accordingly.
Warm Regards
Mandy

Stephen William Hawking is a scientist I admire the most. He was born on the 8th January 1942, in Oxford, England. Stephen is famous for his work on the basic laws of the universe. He is also famous for the way he coрes with having Motor Neuron Disease (MND).

He was a student of the Oxford University, where he studied physics. He was diagnosed with MND when he was studying in the university. It means that Stephen slowly lost control of his muscles and eventually he couldn't walk. Despite his disease, he finished his studies, got married and started a career at the university.

Some years later, he lost his voice completely and it happened when he was in a process of writing his book. He has no way to communicate other than linking. Today, a computer system on his wheelchair enables him to speak. Of his many books, A Brief History of Time is Stephen's bestseller.

His intelligence, bravery and positive to life are the reasons why I admire him. When l think of him, I know that anything is possible as long as you really want it and work hard to achieve it.
