My opinion

We need Dokodemo-door.
It's very useful because we can move wherever faster with it! If there is Dokodemo-door, I would use very much. It takes about 2 hours to go school for me. So I'm tired when I arrive at school. I investigated Sayuri and Satomi. Satomi agreed but Sayuri disagreed. She said ' Because we can't watch beautiful view if we use it. If we take a car, bus and train, we can watch difference views and talk with friends.' Satomi and I convinced. I understood her opinion. I think both of them are important. But I think we are busy, and I don't have enough time to sleep because I must leave home early. Because of that, I'm always very sleepy and I can't concentrate on classes. It's a bad influences. Then we can have worthwhile time because it doesn't take a lot of time to move places. Also, there are no accident so we are safety.
Therefore, Dokodemo-door should be invented and we should use it with limiting the frequency of using.
