Because if you do, the left shoe is the right shoe, but the right shoe is the left shoe, while the left shoe is the wrong shoe, and the right shoe is the wrong shoe, because the wrong shoe is the left shoe even though the left shoe is the right shoe... It's all very complicated. Much better not to do it that way. This is how people end up being afraid of their shoes.
I don't get it. And I *always* put on my left shoe first. And yes, I'm a Southpaw!!! Damn you and your Dextral-centric World-view!!!!
He was fairly active over in TNZ, last time I was over there (which, I admit, has been a while). So, has anyone figured out the OP yet?
Ok, now that I've had my fun, I'll take pity on you poor people and "translate" it into something slightly more understandable. "Because if you do, the left-side shoe is the correct shoe, but the right-side shoe is the remaining shoe, while the remaining shoe is the wrong shoe (to put on your left foot), and the right-side shoe is the wrong shoe, because the wrong shoe is the remaining shoe even though the remaining shoe is the right-side shoe..." The whole thing plays on the fact that both "left" and "right" have other meanings than the one that comes to mind first in this context.
And yet... no one, not even you, was able to understand it. Sounds like a serious case of sour grapes to me.
Anyone who's raised kids could crack that. How many times have we said "You've got your shoes on the wrong feet"? Kid: "I do not! They're the right feet. They're my feet!"
This has been around for a while - it's even in The Bible, but of course there are "thou shalt not" and "verily" type phrases in the original recipe.
