How are you?
So how are you really?
Conversation begins. Putting the really on the end turns the "how are you" from a monolithic grunt of acknowledgement into a real sentence. Try it, but only when you have a few minutes for an actual conversation. "How are you" and "fine" are just the SYN and ACK of human (American English) speech.
Haha! This cracked me up. I bet I would be a lot more social if I could find mappings between communication protocols and human interactions.
The hard part is that style matters. Think of yourself as a web crawler; how do you poke at each webpage to get them to tell you everything you're interested in knowing?
When human interactions are being explained in TCP terms instead of the other way round ;).
