3/6
I updated my old diary moved from mixi yesterday at midnight.
I was so tired that I went to sleep after the class.
I slept 3 hours!
Next, I went to the library to fight my subjects.
I used Maple 16 to calculate production economics homework.
Then, the bad thing happened.
My data has disappeared because of an error!!
That’s why I’m not too fond of Windows…
Goodbye, my 1 hour!
Anyway, I’ll change my mind and study again after eating pizza!
