Well, there's a lot of reasons, but to name a few...

The important documents I was supposed to hand to the supplier suddenly disappeared...

I was busy giving directions to a foreigner, so I was late to the presentation...

I accidentally blurted out that the manager was wearing a wig...

I think you did your best, sis.

Thanks...

You're always so nice to me, Shou-chan...

I'll show them! I'm gonna go to a college in Tokyo and become an outstanding office worker!!

Bye, guys!
