Hello, i have to answer a problem in a few words: "smart phones are used to communicate with people. but what do you think about teenagers who only focus on their smart phone when they are surrounded by friends ? " can you correct the errors and structure the text? you : ) the smartphone is a communication system initially designed to transmit the human voice. it was invented by alexander graham bell. i think using your smartphone when you’re with other people is rude, but sometimes its hard to avoid. its something that has become natural. if one person in a group is using their phone, that opens the door for others, who may start to think it’s socially acceptable just because they keep seeing people do it. it is a habit followed by most of the teenagers of this generation. well, it doesn't make our personality any better too. we send a lot of texts to our friends saying we miss them but when it comes to meeting, we'll all be in the world of smartphones doing something in it rather than spending quality time communicating with friends, orally. we must never ignore the fact that these special moments are to be spent enjoyably when it is possible and not to spend our life inside a smartphone. all this needs to be taken seriously and we must try to avoid the use of smartphones as much as possible when we are surrounded by people to love. also, it is better to advise people that you know to do the same.
