Do you surf online regularly , Joe ?   Of course . I stay online for four hours at least every day .   Are you crazy ? What are you doing four hours online ?   Millions of things . I surf the Net , check my e-mail , and most importantly , I chat with my friends .   Online chat ? Aren't you afraid of meeting bad people who pretend to be what they are not ?   No , I am not . And I love to meet new people in the chat rooms who share a lot in common with me .
