People nowadays use social networking sites very frequently, such as Weibo and Wechat, which have made us more connected than ever. Yet for all this close contact, we are becoming more socially awkward. The harm of replacing real-life contact with virtual conversation, in my opinion, involves two aspects: it made us put on masks and hold up shields.
In a virtual world, we tend to create an image that rarely looks like us. We post messages or pictures to show we are humorous, with a good taste, and living a fabulous life. As a result, we fail to present our real self and dare not to be ourselves. Another unpleasant thing about virtual conversation is that it encourages unimaginable violence of language. The Internet has become a shield in many ways， exempting us from the consequence we should take responsibility for even though we make dreadful and malicious comments sometimes. This undoubtedly mins the quality of social interaction that we need as human beings.
All in all, if we spend too much time interacting virtually, we will dedicate little effort to real-world bonding. Consequently, our interpersonal relationship weakens gradually, and we will end up with unprecedented alienation.
