To change the subject, I didn't study so much yesterday because I spend about four hours in a Chinese restaurant with two of Japanese volunteers. I would like to have gotten home 2 hours earlier to study something, however I couldn't say anything. So while spending there, I thought that I would manage to study about two hours after going home. However I couldn't study enough. All I could do was to check the collection of my yesterday's entry. While checking, I felt sleepy strongly. It was a pity and I'd like to study enough long today.
