telephone is very important because I have to contact to my parent after I moved to stay at dormitory.” She continued “my mobile phone is very simple with the simply functions, but my friends have many. They also persuade me to buy the functional mobile phone in order that we can keep chatting with each other easily, but I think it is not important to me. In case of that, I prefer to see them and dine out with them much more. So, telephone can help release the stress in sometimes, but, we should not adhere to it.
