Do you think saying "Hi man" is polite? Do you think saying "Hi man" is polite? Sometimes, I hear people saying "Hi man" to began their small talks. What's the "Hi man" meaning here in such small talks? Is it just familiar with "Hello"? Plus, it is sure that is an informal expression, but do you think it is a polite way to start a small talk, even we meet a stranger for the first time? Would you like to help me on this issue? Thanks a lot.
