Dear Handbook,
I'm sorry that I haven't kept you well. I always treat you as a fan, a writing pad, a folder or just a notebook. To me, you are like a multifunction handbook. Just because of this, you are now dilapidated; some pages are missing, some pages are nearly off and the book cover is injured. And sometimes I have spilled some water or even soft drinks on you. This makes you have a sticky cover.
Those are all my faults. If I had taken extra care of you, you would not have missed some pages. If I had not treated you as a fan, your cover would not have been torn. If I had placed my drinks well, you would not have a disgustingly sticky book cover.
Your life won't last long. What I have to do is to let you enjoy the rest of your life.
Yours,
Bryan
