A Normal Relationship?

Just wondering if this is how normal friends interact with each other on phone calls.

Danielle: I'm going to have oatmeal. Should I have peach or strawberry?
Me: Peach
Danielle: Ok, I'll have strawberry.
Me: Good, I actually wanted you to have strawberry, but knew you would have the opposite of whatever I said.
Danielle: Well, actually I'm having peach, but I didn't want to tell you that I was having what you told me to.

After much discussion about whether it was normal for us to both try to manipulate the other into having the type of oatmeal we wanted:

Danielle: Does this mean I won? Because I like never win.
Me: I guess.
