Oh! Yes! Ted.
Out with friends on a Dartmoor walk, no trees up there & not much cover, so I nipped behind a rock & asked said friends to keep guard. What they didn’t say was that a scout group had come around the bend in the track & they caught me with my trousers down. My friends were in hysterics!
Another time travelling to Cornwall with son as a baby & we always traveled by night as he slept all the way. I was dying for a pee, so OH pulled off the road in the pitch dark so I could go. I squatted down to pee & suddenly head lights where shining on me lighting me up, I backed up trying to get out of the beams only to fall back into a ditch full of stinging nettles. OH thought that funny too. A little further up the road, once I’d got back in the car, were toilets, those in laybys OH said, Oh! I forgot those were there. I could have killed him.
Erm yes I have. I used to live up in the middle of nowhere and sometimes taking the dogs out, well… when one has to, one has to! Only for a wee though …
I do drive long distances and I do carry a Cuddly bottle in my car but let’s face it going behind a tree in the middle of nowhere is easy enough (unless you are on the Nullabor).
