how to say how are you doing in different ways?
['How are you doing?', 'How have you been?', "What's sizzling?", 'How do you do?', 'Howdy! (This is actually an informal greeting that is short for “How do you do?”)', "What's going on?", "What's new?", "Whazzup? (Just a word play on the regular “What's up?” greeting.)"]
