     Next to e-mail, the most popular activity on the Internet is chatting, which is a kind of social interaction

(社会交互作用). If you ask someone what kind of things they do most on the Internet, they will answer

that they like to chat. This seems especially true of the younger generation. Below are some tips that will

make your chat experience friendly and fun.

     Walking into a room and demanding age and sex (性别) is the most common mistake a new chatter makes.

Most regular chatters will ignore (不理会) the question and you. Don't limit yourself. Talk to everyone in

the room equally. You will soon know who shares your interests and who doesn't. If you prefer a one-on-one

type of online friendship, then maybe you'd better look for pal (好友).

     Shy? Many people feel shy when they enter a chat room where everyone seems to know everyone else

except him. It's really easy to feel left out. The best way to lose that feeling is to make yourself feel that you

are not a stranger. If you enter a room and say "Hello, everyone! My name (nickname here) and I'm new."

You will find that there are a couple of friendly people that will be happy to help you become part of them.

     Basically the best way to have a good chat experience is to be yourself and friendly. Try to join in the

conversations going on and don't be afraid to ask for help. Do remember, however, not everyone is nice and

friendly. There are also going to be a few people that are rude and just make you feel rotten. The best thing

to do is just ignore them. Arguing with them will just make it worse. Show that you are better than they are

by just refusing to let them get to you.
