I've been studying English for 1 year and I'm good at it. Anyway, I would like to know how to greet in some ways. I greet in 2 ways usually:
- Hi, What's up?/How are you?/What's about you? Not bad, You/I'm not good/I 'm very good. (Informal)
- Hello, How are you? I'm good, thanks, and you? (Formal)
Are there different ways to greet formally? I would like someone list me some ways most common to greet formally (Example: When you're speaking to your boss or teacher), thanks!
