A Text book confused me.

I spent a lot of time to solve an assignment of computational geometry. The textbook had some mistake, so I had to fight my code of a program until I noticed the mistakes. Some hours was waste because I believed textbook is true.

Trip

I was told from a friend about his trip. He went to a short trip by his bicycle today. He said he ran about 50km proudly. He showed many pictures of the trip, but almost of them were Shinto shrine's pictures. I do not know why he took only such boring pictures. I also want to go to a trip like him. I have to buy a cheap digital camera at first.

Broken mp3 player

My mp3 player was broken when I ran around the university. Vibrations when I was running was the cause. A lot of my music data was lost then. I will never run having that.

Ran around university

I trained at university training room, but someone have used running machine already, so I could not use it after a warm-up. I did not want to wait him, and I went to outside to run around the university. It is almost 2km. I spent ten minutes to go around the university. It was a little shameful to be looked from someone or friends, but it was very comfortable. It was different from running on machine at all.

Cleaning

I cleaned my room. I have not cleaned for three weeks, so my room is very messy. It was a good chance to take out my kotatsu from my closet after cleaning. It is so comfortable that I become sleepy in my kotatsu.
