How many times have we gone over this...
I always thought T and F were just how you approach the world.
T = Objective approach (same screwdriver should fit all screws).
F = Subjective approach (Maybe this little special screw driver is too delicate to use my leatherman on it. Let us try an eyeglass screw driver. Turns out that the screw gets offended because in reality, its a tough SOB and doesn't want anyone treating it like a baby, who would have known that screws can be NT).
