Speaking of online communication, there were a lot of interesting things worth taking about in the last 20 years. I still remember the first time I had a chat with others online 21 years ago. At that time, I was in high school and always felt depressed about my academic work. People around me included my family couldn't understand me . In that case, I got a social media account and tried to meet someone who were the same online. Fortunately, I made some friends ,and we shared all of our thoughts and anxiety about high school life. I felt relaxed and finished the rest of my academic with a great mood. So, I got a lot of benefits from online communication before. Nowaday, we concact others by using social medias everyday, but I seldom share personal things with others online. Social medias has just turned into a tool that used to communicate something about work for me. I can't get the feeling that could hlep me ovecome the hardships 20 years ago. Though I am always under press due to work, family and other things, I really don't want to share anything online. Maybe an adults' world can only be full of loneliness. Sometimes I write something on a notebook at a slient night , I just want to communicate with myself by this outdated way.
