Since that very Christmas, Sheldon did indeed changed his ways.
Although he was still quite the genius he was, no longer was he the cold and standoffish person he once was.
In fact, not only did he become warmer and friendlier, but was always now willing to lend a hand to his fellow colleages, making him to become well respected in his field.
His relationship with people had change, as now he was more enjoyable to be around, which included his family, friends and Amy, who's relationship with Sheldon became more meaningful.
The two of them actually got engaged the following Valentine's Day.
Sheldon's other friends did well in their careers and personal lives as well.
Leonard became very well known in his field as well, even reciving an honory award, to which his mother was very proud of, as their mother/son relationship had gotten better.
And while he was popular on in the world of science, his wife Penny became very big in show business.
First, by appearing on the cover of a bridal magazine(while shopping for a wedding dress), which got her a recurring role on a soap opera, and later recieved an Oscar nomination for playing Jennifer Lawerance's sister in a movie.
Raj remained at Cal Tech for the 5 years Sheldon got him, and more when he became the head of his department, when the head professor in his field retired.
Raj was also happy with his personal life, as it turned out the date Stuart had for New Year's turned into a double.
He fell madly in love with Wendy, a comic artist, and the two of them are still together.
Stuart's date with the spider man fan named Katie(a photographer) went very well, and they got engaged the following Christmas eve.
As for his business, Stuart's comic book store countinues to thrive in business, especially that not only did he open a second location, but has become a very well known local artist, releasing his own work.
Howard and Bernadette also did very well themselves.
He was named the head of his department as well,(which actually earned him a great deal of respect from Sheldon) and she was named co-chair of her department.
The two however were hit with sadness when Howard's mother suddenly passed away of a heart attack in her sleep.
But happiness returned when Bernadette gave birth to their daughter Halley Deborah.
As for Sheldon's feelings on Christmas.
Like his personality that to had changed.
No longer does he despise the jolly holiday season,but now embraces and relishes it dearly.
And there is no one now who keeps the true meaning of Christmas close to their heart as Dr. Sheldon Lee Cooper.
The End
