INTP: *driving*

INTJ: *thinking* ''Hmm, some road construction signs.'' *notices a trench across the road where it has been dug up and filled in with gravel* "I wonder if they will notice that." 

*car rapidly approaches trench*

INTP: *slams on brakes just before trench and bounces over it "^%*#! Where did that come from?! Why didn't you tell me?"

INTJ: ''I wondered if you would notice that." *laughs*

INTP: ''I was thinking.''

~ an hour later, coming back along the same road ~

INTP: *still driving*

INTJ: *still looking at the road construction signs* "I wonder if they will remember this bump in the road. Doesn't look good, though.''

INTP: *again slams on brakes just before the trench and bounces over it* "Oh hell, I did it again why didn't you tell me?"

INTJ: "I can't believe you did it again." *laughs even harder*
