OK, I admit it: emoticons   are popular. Some people even think they are fun. Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications. Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast   the use of emoticons as "infantile   just like the people who use them"  He believes that words themselves should be enough. "If you're being funny, happy or sad, that should be apparent   from the comment that goes before the emoticon," he argues. In the eyes of Blumenthal, the use of emoticons is a gender issue. "Men don't use emoticons very much. Maybe not at all," he said. "Teenage girls and women seem to use them a lot. Maybe there' s an emoticon gene." It's an interesting opinion, but it is not shared by all. In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed "to seek out representations of humanity". He believes that they appeal not because they are shortcuts for the lazy, but because they tap into   something beyond language. They reach to our need to be with and communicate with people. All of these arguments may be somehow valid  . Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I'd rather let my words do the talking. Friends, however, send me messages and e-mails full of emoticons. I have no problem with this. I don't regard any of my friends as lazy or immature  . It's just a question of individuality. :) From the text, we can conclude that the author   _  .
