Hmmmmmmmm, Cady.... so you're into handcuffs, eh?
I agree with what you said, but the possibilities with these skills branch out like a bush, so there are few people who truly get to the "is that all there is to it?" stage. It's truly complex and deep, even though it appears to be just a puddle in the road to the uninitiated. That "puddle" can be the entrance to a set of underwater caves.
Best.
