Except, if you walk into a hardware store and ask for "a three leaf hinge", they wont know what you are talking about and they will try to sell you a plantation shutter hinge which is something completely different.
For all the "progress" Mankind has made, we have forgotten twice as much of what we used to know. For instance, hand a 12 year old an old rotary telephone. They will be all like-"What the $#!+!!!??"
ETA, speaking of which, how come we still "dial" telephone numbers? Can't you just push the buttons?
