The Only Question I Have If I'm Stuck In a Desert

I have a question....

Let's just say.... we're out in the desert...

Freaking out in the open.. with just sand all over you..

And suddenly.... you have the urge.....

out in this open sand... you have the urge to shit....

Where do we go again?

Now, I know how we do it in the jungle,
I mean with trees and bushes... that's never a shortage for cover... If you get what I mean..

But to be out in the open... with only sand...

Here's another what if...
What if, you ran out of water.... or water is really in the "Please do not misuse" situation..

And there's no toilet paper....

I mean.. if it's in the jungle.. there will be leaves or sorts.. you know, for substitution...
But the desert....????

Any comments are appreciated, (be creative) LOL.

Cheers.
