Yesterday, I took a day trip to Kitakyushu with my son's girlfriend.

Before the surgery, my son had said that he didn't want to meet anyone till he got convalesce.
Certainly, on Tuesday, the next day of surgery, he didn't look well. So, I decided to go to see him once more this week. Because I knew that his girlfriend wanted to go with me, I asked him whether I would take her with me, or not. He didn't. I apologized her for waiting for more week.
However, on Wednesday, I got an e-mail from him.
He asked me to bring her to him because he got well more than expected to take a shower and to start physical therapy.
I laughed my head off and I got so happy!
I left them in his for-bed-room after saying them to be careful in his four-bed-room because there were only curtain(drape?) not sound barrier.
My son thanked me all, and I said to him,  "Don't mention it!".continuing from last week.
