This is me saying
It is a greeting and also
an invitation of sorts
Hello can often mean:
Please start a conversation with me
You could share personal information
Ask me questions about my interests
Discuss current events
You might ask me about the weather where I am
Example: It is sunny here and has not rained in days
I expect the sunset to be beautiful here this evening
How do things look where you are?
I meant the sunset,
how does that look?
