My father was a voracious reader of books. Even if he couldn't go out and lie in bed, he read many books until he died.

One day he asked me to buy some books at a bookstore and handed me some ad scrap of books from the newspaper and his credit card. And also he said I might buy a book that I want together.

Ok, I went to a big bookstore at the next station, walked around some corners, gathered them, and added my one. At the register, I thought I had my father's credit card and didn't hear his identification number. The clerk checked and handed me to sign.

 I thought, "Don't worry, calm down, just to be my father."
And I signed completely like my father's signature.
His signature was so characteristic, but I could do it. When I think about it, I still don't know why I could do it.
