The first technological device that I started to use was a mobile phone when I was a high school student. It was an old-fashion one, so called "Gara-ke" in Japanese. It was not like a smartphone nowadays, and there were few applications in it. However, I still thought that it was a great innovation for us. The reason why I started to use it was because almost all my friends started to use one at that time and I was keen to connect with my friends through the device. It did not take much time for me to get accustomed to manipulate it. It was very useful since we no longer needed to make appointments with friends in advance. In addition, it became rare to keep our friends waiting. Thanks for the innovative tool, which enabled us to text whenever and wherever we were. I appreciate the great technological innovation. ------------------------- Thank you so much for reading my notebook. I appreciate if you could give me any advice to make this writing more sophisticated with using more less common words, idiomatic phrases, and complex sentences. Thank you so much for your help.
