I think my estp friend summed it up best last time we hit a drive thru.
He stated that I always know ahead of time what I am going to do, in this case what I would order, whereas he decides in the moment.
Te by nature is the simplest form of logic and decision making. In it's most basic form it thinks in steps and cause and affect and usually has decisions worked out many steps down the road. That is why many of us who have not developed our second functions sufficiently can seem mildly retarded. I am joking a little but without some Ni or Si thrown in for perspective, we can totally lack any form of creativity whatsoever.
