Social media is an invention of the 21st century, why do we need social media? Social media is used to communicate with each other. We use social media to show our lives. We share information about our lives with other people. Sometimes, different problems arise because the information we share is not always well thought out by us. We check how many followers we have, how many likes we have, how many friends on the list we have, many people use social media for work. Many people can not imagine life without social media. Many people using social media are affected by a wave of hatred. I do not use any social media and I live somehow.
