There’s nothing like ‘hitting the wall’.  It’s a rather quaint expression used when you have used up all your energy and there’s nothing left.  A lot of sportspeople are very familiar with this expression.

But it doesn’t have anything to do with hitting a real wall, you know the sort, made out of plaster, or bricks, or timber.  Some people hit the wall in this case too, and soon find out what it’s like to have a broken hand.

There’s wall street, you know the one, it has a bull in it, and it’s in New York, down that end of the city where the Twin Towers used to be.  It’s rumoured lots of ‘jiggery-pokery’ goes on there.

Try stonewalling, you know, give answers to questions that don’t answer the questions, or find something else to do and put off being questioned.  I’m not sure, however, that’s how Stonewall Jackson got his name.

We can climb the walls, metaphorically speaking, but it is something we don’t actually do when we’re bored.

And, I’m sure everyone has heard of the Great Wall of China.  Even those who travel in space have seen it, from a long, long way away.  I’ve tried walking along it, and up it, yes, parts of it go up the sides of mountains, and it’s challenging.  Maybe you should try it sometime.

Perhaps a few others, just to finish with, like

I got hit by a wall of water – yep, watch out for them tidal waves

There’s a wall between us, nope, not gonna talk to you
