What's your greeting?

[Lamb]

When you're out and about, what's your greeting toward people? Hi, Hello, Good Day, How are you? etc...

 

[Messy]

Hallo hello
Goeiemorgen good morning
Goedemiddag good afternoon
Goedenavond good evening
Mostly I say back what they say and when I say it first I noticed they say the same thing back.
