Inappropriate Responses

I so do this.

I’m often in my own little world. Usually no one can tell. One of the ways I give myself away is that I respond to what I assume people should be saying instead of what they actually say.
The FedEx guy just delivered a package. When I answered the door I expected him to say something along the lines of “How are you?â€? So our exchange went like this.
FedEx Guy: “Here.â€?
Me: “Good, and you?â€?
