"A man's a fool whose sheep flee's twice"

Thanks to help from family members, and my own knowledge on shepherds, sheep, cows, electric fences, and Spanish, I have reached a conclusion on this proverb. It means that you shouldn’t do the same mistake twice. To learn from your mistakes.

When I was given the proverb, I had no idea what it meant. I mean, what would it matter to me if the dude let the sheep left him? Was he really that lonely?  And so, I went to go ask for help. I was told a whole bunch of stuff, which I don’t remember, because I had no idea what it meant. It just sounded like Xhosa to me. (Xhosa is a very complicated language spoken somewhere in Africa. I couldn’t think of any other language to which I knew absolutely nothing to, not even a random word) At my baffled expression, my mom tried to explain with a different technique, or better, I do not know which, as I have no idea which way she explained it first. She asked me to translate the moral to Spanish.  And with this I reached a conclusion. The man is an idiot. And then she told me something around this: “ If a Shepard is at his job, and falls asleep, or leaves the gate open,  letting his sheep escape, the next day he will know not to fall asleep or leave the fence door open”  Thus, looking at me with an expecting face. Me just looking back at her blankly, she sent me to my dad. He had heard our conversation and decided to use a different example. Cows and fences. “If you put a cow inside a fenced area, at the beginning, it will run at the fence, and get an electric shock, but it will try again and again, and eventually give up, because it will have figured out that fences = electric shock” To this my mom said a witty comment (I’m guessing) to which they started laughing, but I found no humor in. I’m not sure why, but then it all clicked, how could I have been so dumb. The ‘man’ is a Sheppard (easy take). His job is to keep the sheep’s from running away. The ‘sheep fleeing’ refers to his mistake. And the ‘twice’ is well, it means two times. The Shepard failed his job twice. He’s a ‘fool’ or idiot for letting the sheep run away two times; He is an idiot for making the same mistake twice. He should learn from his mistakes. Tada!
