When I'm not distracted by a computer game or something, I get a fairly good estimation what kind of pizza I want. "I want something fresh. mmhh with tuna. But no onion or garlic today, what are the options?"
I have a problem when the pizza man arrives. Like when I'm playing a computer game, I'm rather serious and concentrated on the game. When I talk with people, I just exchange information, I don't pay much attention to expressions. And then the pizza man arrives - I can't go to the door and not even smile to him? I can't talk with him in a dull voice! That would seem so rude! But I can't figure out if I should temporarily turn into: happy and cheerful (and get it over with fast), practical and calm, friendly and naive "ah, pizza? Great", etc. I could become any of those, but I don't know which one the pizza man would be the most comfortable with.
And all those are different versions of me. None of them are fake.
