Human beings are social animals. We will make friends in different activities. When we were children, our classmates were our friends. When we got jobs, our colleagues were our friends. Now, that we are living in the digital world, we make friends online. More and more people are prone to making friends online rather than attend different activities to make friends. There are two reasons behind this phenomenon. First, making friends online is very convenient. People do not need to attend real activities. They can make friends on some online platforms. For example, people can go to the Italki website and find friends. They can find friends who also want to learn languages. They can share their experiences to their new friends and also become partners. People just need to use their smartphone and go to the internet, then they can make new friends immediately. Second, people will not feel pressure when they make friends online. They cannot see each other. They communicate by typing. If they do not like the guy they are talking to, they can leave the conversation, and search until they've found the right person. People feel comfortable in this process. They do not need to talk to the person they do not like.
