Recently, I wrote that I bought some old books from used book stores.

I noticed at this time of day, that some of the used books are not worth reading until the end of pages, because the books were sold off.

In my opinion, many of the old books were read one third of the total.

I could find it from fill-in or stains.

-----

What I did is to throw the books into the wastebasket.

As a matter of courtesy, I used to read the whole pages of the book.

Though some persons might say "you don't have to act like this", I believe that I have to make the book extinct with my own hands.

I do fancy myself as Aoshi-Shinomori in Ruroni-Kenshin.
