A Stare Is Not Necessarily A Glare

Back when I first left the Foreign Legion in North Africa, I spent some time wandering around some of the more picturesque (scenic) places, while at the same time avoiding any war zones. At one point I was traveling by jeep through a desert landscape (the surrounding area was desert, in other words), when I came across a small and strange looking man. He looked Arabic, but with his dark hair and skin, he could have been Spanish, Italian, or even Greek. Heck, for all I know, he could have been a Bushman.
Anyway, or anyhow if you prefer, he happened to be beating a horse that appeared to be dead. I stopped the jeep, and asked him what he was doing. Without even pausing in his assault upon what was, indeed, a dead horse, he just glared (a menacing stare) at me for a few moments, and then continued to give the horse his full attention. Feeling that it wasn't really any of my business, I continued on my way.
After having a wonderful dinner in an outdoor cafe, in a beautiful North African coastal town, I was returning back to the east, from where I had come. On the way back, driving through the desert, I saw that same strange man with the dead horse, again. Only this time, it looked like he had been cooking it over a fire, and was busy eating it. I stopped, and might have said something, however, before I could even get my mouth open, he started glaring at me again. I didn't really appreciate his attitude toward me, and I did feel slightly threatened. So, I just drove away.
I have, of course, heard the expression about beating a dead horse. Meaning, to continue on with something long past the point it can do any good, or accomplish anything of value. But I've never heard of eating the dead horse, after you beat it. I suppose that's one way of getting rid of the evidence. As the French say, c'est la vie (that's life). Except, of course, for the horse, who was no longer living.
