I try to say what I mean, and mean what I say.
Sometimes I just want to say "Hi" or "Hello" without asking the person how they are going. I like to ask how they are or how they are going only when I am genuinely interested in hearing the response.
The thing is, if I just say "Hi", it can seem curt, or awkward, almost as if the expected greeting was "Hi, how are you?" or just "How're you going?"
How do I politely say hello without asking somebody how they are?
There are three cases:
When I want to be polite and acknowledge someone's existence without engaging in a conversation.
When I intentend to interact but have no intention of asking the person how they are in the current interaction (eg avoiding asking a person who is a chronic complainer)
When I want to ask them how they are later on, perhaps when we are seated, in a quiet space with less distractions.
I live in a community of international travellers and expatriates.
