The doorbell was ranging in this morning.
Then I made sure who was standing outside.
A deliverer was standing.
And then I opened the door.
(Everything was usual.)
Next, the deliverer requested me to put my seal on a slip.
And so I put my seal on the slip for receiving my package.
(It was regular act as everybody knows.)
After that, the deliverer turned his body and he nearly returned to his car
without delivering the package.
He realized quickly about his mistake and said sorry to me
with smile for hiding his embarrassment.
Finally I got the package without any trouble.
