I see more and more people almost spend all of them time on checking their phones except falling asleep. Different people have their own different favorite apps for entertainment. The online world is much more interesting than the real world for them.among these apps installed on our phones, the communication apps which also called social medias have become one of the most important parts of our daily life. I can't imagine how I made friends with others before smart phones. During that period, only the people around me potentially could be my friends. A friend must be the person I met in person. But everything changed after smart phones got into our lives. Nowadays, we have a lot of friends online. Most of them we never see , even have a picture of them. We share the interesting things with each other, and cancel these ones we don't like. On the other hand, I slowly find that I am afraid of seeing my friends in person. I even forget how to communicate with friends, because I read an article about some tips of starting a conversation last week. I have definitely lost an important skill due to smart phones.
