. . .

I was about to go home.

I was standing outside that room.

She was sitting in that room with her friends, and I don't know any of them.

I was thinking whether I should go in and say goodbye to her once more. (I already said goodbye to her, but then I came back to take my bag), because I didn't want to interrupt.

Then I remembered that I wouldn't come back the next day.

That was when I was standing outside that door, looking in.

That was when I felt so damn sad.
