'hey' ( perhaps originally a natural expression) appears to be at the origin of 'hi', while 'hello' seems to have no connection with the previous two terms and a different origin. Hey, haven't seen you in ages! How are you doing? i haven't seen you since the funeral — how are you doing?.
I really want to know what's the difference between hi and hey in writing an email? 天天在我耳边说 man, man, what can i say,问他是什么意思又不说。 I am not a native speaker.
It can be used as either a pithy bon mot to jostle a friend, or a snide comment to completely distract and put off a mere. How are you? versus sorry to hear about the diagnosis. It seems like the correct spelling is “but, hey,” however, especially when followed by a clause, the pauses (perhaps) become excessive and the comma is frequently dropped. Is it too girlish or childish for a man to say.
