earlier - A greeting, like when you're trying to be polite but you're

A greeting, like when you're trying to be polite but you're also kind of lazy and don't want to say 'hi' properly.

Earlier, I walked into class and said earlier, my teacher gave me detention.

Earlier, I greeted my crush and now they're following me everywhere.

Earlier, I said earlier to my dad and he said, 'You're going to regret that.'
