In past time, I was in the room.
The room had no windows, and I put a plate "Don't disturb".
Do you know the movie "Dancer in the Dark" ?
Bjok sings in the movie,

"I've seen what I was - I know what I'll be

I've seen it all - there is no more to see!"

"I've seen it all, I've seen the dark

I've seen the brightness in one little spark."

I didn't know what I'll be.
I haven't seen the brightness.
So, I failed happy graduation.

Sorry, the rest of this talk is next time.
