In the last class, we learned about perception. We watched some videos and fun magics. Magics showed the importance of observation from a different angle. When I watch carefully from other angle, I will clearly understand things that looked strange. The reason why we enjoy the video that explain the behavior in sushi shop is we know real behavior. If we do not know actual action, we cannot take pleasure in it. I watched two videos about dangerous situation. Though I thought it was dangerous, they might think it was enjoyable situation. It showed that each person receive different impression.
