Change schedule

One week before going back, I have to change my schedule. I thought it is quite OK to me since it is my fault but now I am really sad. I should ask my supervisor before I booked the ticket. I am very sorry about that. He is so busy and he had to modify my thesis. On the evening of this Monday, when I find that he had modified every tiny mistakes in my thesis, I was moved. He is always a nice professor. I think I'd better change my schedule.

It doesn't matter. It is not necessary a bad event. Anyway, I am not at all prepared for going back yet. It is not such a big deal. Bless!
