Did I lose my bankbook?

Hello.

I finally found my bankbook in my parents' home where I have been left a part of my things.

I looked for it several times before but I couldn't find.

I have been wondered if I might have lost my bankbook somewhere because it needed when I regist my salary account.

I used change my job often.

Usually, I don't use bankbook, but the situation was not comfortable.

It was solved. I am so excited.
