The three flavors of social interaction

Guy1: "Good morning."
Guy2: "Huh."
Guy1: "Can I have a muffin?"
Guy2: "Where you from?"
Guy1: "Here."
Guy2: "Hehe. No you ain't, come on."

Guy3: "How are you today?"
Guy1: "Pretty good, thanks. Nice to meet you. What's your name?"
Guy3: "That's fantastic. I was wondering if you were interested in coming to church sometime."

Guy1: "Morning."
Gal1: "Morning! I was wondering if you would like to purchase this metal doohickey for a thousand dollars." (Insert gloriously fake smile.)
Guy1: "Wow that sounds sweet. What's you name?"
Gal1: "This metal doohickey comes with a plastic whatchamacallit for only 999.99." (No smile.)

Those three cover 99% of the conversations I have most days. A fourth variety is something like this:

Guy1: "Miss, I sent you an email an ice age ago about the project that everything is riding on. Did you have time to read it?"
Gal2: "Yeah it sounds totally fine. I can't promise that it's exactly fine but it seems fineish. Totally."
