Super Defensive Thinker

I wonder if there's a person who ALWAYS thinks:

If this person asks me this, I'll tell them this

If this person asks me why I'm doing this I'll say this

I'll say this if that person asks me this

When they ask me when I'll say this

And so they come up with premeditated responses..

Is it some kind of disorder to think that?  Or do normal people actually think of this, and that's how their conversations go so smoothly?
