Duality!

I walked in. You looked up. You were sitting at the same place. I came over and sat across the table. You said "Hey,It's great seeing you!". I smiled. You ordered. I told you something. You laughed. I smiled. You said something. I din't hear you. You repeated it. I heard it then. You were offended. I took my leg and ran it over yours. You did the same. You looked into my eye. I returned your stare.
