Malala Yousafzai's story will always be an inspiring one.
But today, she attended her first lecture at Oxford University.
The Nobel laureate got admission at Oxford in August this year to study philosophy, politics and economics after she was interviewed for admission earlier in the year.
Five years ago, Malala Yousafzai was on her way to school in Pakistan when the Taliban shot her in the head in an attempt to murder her for the sole fact that she believed women were entitled to the same education as men.
Within hours of the tweet, over 112,000 people retweeted her message and over 354,000 people liked it. Thousands of followers congratulated her again in the comments, calling her an "inspiration" and a "beacon of hope". Fortunately, she survived and won the Nobel Prize at the age of 17 three years ago.
In what was kind of a humorous and sweet exchange, her younger brother Khushal replied to the tweet, apologizing for being a headache for the last five years. So grateful you are still with us. He jokingly said that he too would be coming to Oxford in two years' time.
In 2012, Yousafzai was shot at by the Taliban for her advocacy of girls education in Pakistan.
Fearing reprisals in her native country, she made Birmingham her home after she was treated at the city's Queen Elizabeth Hospital.
