I have a cell phone and have to pay about thirty dollars per month to use it. Thirty dollars per month is no small amount of money for a student. To be honest, I don’t need to use a cell phone because I don’t have any urgent business, but all my family and friends have cell phones. More than fifty percent of the population in Korea has a cell phone. Think about that number; only children and very old people don’t have one. If I did not have a cell phone, everybody would raise such a question, "Why doesn’t she have one" I would be considered a strange and independent person. Korea has a group oriented culture, so a strange and independent person isn’t welcome. I don’t want to be strange, so I cannot do anything but use a cell phone. I have to check my cell phone all the time, and I have to change the battery every other day. It is kind of a big problem. Even though I don’t want to answer the phone at all, I have to answer it because as long as ! have a cell phone, a quick answer is etiquette. It has really invaded my life. I have never thought cell phones are useful and meaningful devices. I hate them because I arn a person who likes to lead a peaceful, calm life. I wish I could get rid of my cell phone in the near future. Why does the author think having a cell phone is a big problem
