Article: One day I heard that one of my dear friends had lost his mother. This made me sad, for my friend was very close to his mother. He had been by her side as she traveled through her long and hard journey with cancer. At this time, many memories about my loved ones that had passed away came flooding to me. Finally these memories passed, but it was really sad to think that my friend would have to go through the pain. Three times I tried to write an email to my friend and three times words failed me. I am a person who is not often lost for words and I decided to have a sleep. Upon waking up I could hardly wait for my computer to work, the words I needed were there. I was still left with a heavy heart although I had sent an email. They say that everything in this universe is balanced and indeed it is. Three days later, I received his reply letter. I was happy to hear that he'd been admitted to Cambridge University. It served as a gentle reminder for me that my friend would be okay and that life would go on. Everything in life is balanced; the lowest feelings change places with the highest feelings. Without the lows, we would never appreciate the highs. No matter how dark the clouds seem to be, the sunshine is always there and just waiting for the opportunity to shine through. Question: From the text, we can learn that the author is _ .
