W is my co-worker and friend,and for some reason I have to live with her in her dormitory for some time. After I moved in , I found she had a very bad habit. She is crazy about the computer games. As soon as we get to the apartment, she will sit before the computer and get into the games.At frist, I don't think it's a big problem, after one day's hard work, we do need to relax, while she sit there for the whole night without doing any other things but playing games.Every night so , she goes to bed at midnight but will keep the computer on and the games continue automatically, the next day morning, the first thing she will do before going to work is to check the game process. I have no intention to interfer with her habits, while she is so addicted that already affected her normal life. Because games is her only life outside work.As her friend, I do want to remind and help her, but I'm afraid I will annoy her, no one likes people to disturb her private life, what should I do ? Keep silence or persuade her?
