Have a nice day!The Internet Harms Friendship While the Internet can bring people closer together, it can also harm friendships. Firstly, talking online is no replacement for face-to-face contact images really cannot replace a real-life smile or hug. According to a parenting expert, Denise Daniels, communicating through a screen makes it more difficult for children to concentrate or show kindness to others. As we know, important social skills are developed through direct contact with other people. It is these skills that enable us to develop lifelong friendships. Secondly, the Internet can make people self-centered not thinking of anyone or anything but themselves. For example, instead of having proper conversations with their friends, some people are only concerned with their online popularity How many “likes” did I get? How many followers do I have? though we know that the number of “likes” or followers cannot compare to having long-term and rewarding friendships. In addition, a lot of the content posted on social media is shallow or trivial. Posts about funny cat images do not necessarily help form meaningful relationships. Thirdly, online relationships may not be what they appear to be. Friendships are built on the basis of trust, and with online communication you can never be 100 percent sure that the people you are chatting to is being honest about who they are. Because of this, going online can be particularly dangerous for people who are easily influenced or too trusting. In my opinion, friends should focus more on face-to-face communication, and less on online communication. This is the best way to maintain healthy relationships. The Internet ________ Friendship The Internet can help develop friendship in many ways. Firstly, the Internet makes communication much more convenient. You can stay in touch with friends no matter where you are or what you are doing. Using a smartphone, a tablet or a computer, you can be in contact at home and also when you are on the move. Secondly, the Internet has also made communication more fun. Traditional ways of communicating, like letters and phone calls, can be limiting and take time. However, you can share photos, videos, news stories and websites with your friends online. You can give a brief response to a message with an emoji or a picture. There are so many online tools you can use to be creative! Thirdly, online communication can actually bring people closer to each other. Nowadays, your friends are just a click away. Whenever someone needs help, friends from all over the world can immediately provide useful suggestions or information. This makes friends feel loved and cared for. To me, this is a very thought-provoking argument, as it points out the benefits of online friendships. As Eileen Kennedy- Moore, an authority on the subject, points out, online friends “fill holes real-life cant”. Finally, I believe the Internet brings people closer together and makes communication with friends more convenient and interesting.
