This week, I have a two big event for me. First, I exchanged my smartphone. The before one was using about 4.5 years. So battery's condition was very bad. The new one is very nice. Battery is so long, and screen size is wider than before one. I said, "I want to exchange my smartphone!" since this year's spring. At last, I changed it. Recently, smartphone and other machines are too expensive to change easily. So I changed old smartphone's battery at 2 times. But battery was doing worse quickly. Second, this weekend, I will go to my favorite game event in Chiba. My favorite game's name is "THE IDOLM@STER" series. This game's event will be held in weekend. It will be held in Makuhari Messe. Makuhari messe is located in Chiba pref. Near the this facility, you can see a big Tokyo Bay. But there is very windy because near the ocean. So you should wear windbreak outer if you go to there for some events. This week is too busy to me. Additionally, I had part time job for three consecutive days. It was very hard. But I think that this weekend's event is reward for me. I will enjoy that event.
