Each different period will bring difference in interaction between people. The development of technology and the foundation of the internet has changed the way people contact with each other. In my opinion, the release of internet impact on people's relationship very much. Back to the early 20th century, the relationship of people base on the exchange of letter and keep in touch with each other by public telephone. If we're stay far away from each other, it's really hard to meeting face to face. Traffic is underdeveloped and the travel's cost is very expensive. It's take a lot of time if we wanna meet a person staying far from us.
But since the internet was invented, everything gets easier. The birth of the internet and social media bring a lot of benefits to human's life and people's relationship. This is a positive development. Facebook is a representative of the development of science and technology. With Facebook, we can see the one who're far away from us, like in the other country, or in the other continent just with one video call. One click and the one you want to meet will appear in front of your face. It won't take to much time to contact with others and we don't have to waiting so long for someone's information. It's much convenient when we're having Facebook and other social network application. But we shouldn't to abuse it, such as if we're stay close, we should meeting face to face, talking to each other and showing our feeling in a most practical and obvious way, not through a screen or texting. In conclusion, the birth of internet and social network application make people's relationship better and bring people close to each other. The positive of it is countless. But we need to use it in a right way to make everything better.
