Forgetful

Two days ago I lost my check book. It’s a new one, just received that day. I looked for it everywhere, but still could not find it, yet I had to open a check to pay my house insurance.

I was pretty sure that I left it downstairs and had not brought it up to my room. I checked everywhere (downstairs) and still could not find one.

I already thought to call the bank and asked them to send another one, until I cleaned my room, and …. I saw my checkbook under my older daughter table. How could I totally forget that I already brought it upstairs, I really have no ideas.
