Welcome to the forums, Slim.

Very interesting question. I'm really curious about that one myself. It is actually a very funny saying.

It sounds like she got away from him, escaping his very grasp.

Let's wait and see what some more knowledgeable forers have to say.

Thank you very much for the welcome, hhmdirocco. I am curious to see if anyone has heard this or knows what it means...

Here is one possible reply:

Donkeys are also known in Mexico as evidence. I'll explain: when someone says he's sure that someone did something not exactly aboveboard, and that he has the evidence to prove it, he says: 'Cuando digo que la burra es parda, es porque traigo los pelos en la mano.?

I took this from this web page:

Does this work for you?

Thank you Moe. That could very well be what this person meant. I appreciate your help!

if I tell you something is so, it's because I can prove it?

Any help would be appreciated!

Thanks!!!

Hi slim, welcome

Yes, this is exactly the case, you have answered your own question.

We also say this funny sentence:

blanco y en botella = leche

Like , listen, there is no prove necessary, it is obvious.

Thank you Heidita, for the reply and the welcome. It all makes sense now
