INTJ: I just stuck the end of my iPad charger in my coffee cup.

INTJ: It made a cute plopping noise.

INTP: Is the J turning into a P? That sounds like something I would do. 

INTJ: No, my hand slipped.

INTP: Ah. I would have probably done it purposely while not really realizing what I was doing. 

INTJ: Also my estimation of the fullness of the cup and the length of the cord was off.

INTJ: "I wonder if I can make really good coffee by plugging it into this outlet 
here . . ."
