2016

 "What is this?" I found an old book. I thought the owner of the book hadn't touched that book for more than 3 years. But when I read that book, I realized that it was my diary. I took that book and I read it carefully. I wanted to change everything. 

 "I wish I could go back to the past," I sighed and closed that book. Suddenly I heard someone calling my name. I didn't know whose voice it was. But then I saw something coming from the window. It was shining. I was really scared, I couldn't even move.

The light went brighter and brighter. I couldn't take it anymore, it was too bright. I closed my eyes and tried not to look at the light. But then I heard someone calling my name. I opened my eyes and the light wasn't too bright anymore. I got really surprised when I saw a fairy. Yes, a fairy!

 "So you want to go back to the past?" That fairy asked me. I nodded nervously. That fairy then grinned and told me to close my eyes again. 

When I opened my eyes, they widened when I saw the calendar. 2011?!

Oh my God. I really went back to the past.
