how to chat?

Answer 1

I assume you mean online chatting. First of all, it depends on who you want to chat too. Think about what sort of person you would like to chat with, is it for friendship? Or to meet someone? Then, look up chat rooms on yahoo or any of the search engines. Your question is so vague that it is difficult to answer.

Answer 2

start with "Hello"
and the conversation personal (not sexual) in the fisrt three lines
then the talk will flow on its own

Answer 3

you open your mouth and try and make sounds like ugh
