After many years of absence, my sister-in-law, well known as a very loving mother and for having an explosive personality, went to Venezuela with her two little children. They went to visit a famous museum in downtown Caracas, which is now a pretty dangerous place.
When the cab stopped in front of the museum, she stepped down with her 180 pounds of weight and a big smile on her face. Then, a tiny thief approached her and with a ferocious grimace, put a big knife in front of her face and shouted: "Okay, cow, give me your money or you won't live to tell the story!"
Calmly, the 'cow' turned to the cab and told the children to stay still; then turned again toward the aggressor, made a quick movement in karate style and yelled: "Su-mooo!"
I cannot repeat what the scared thief told my sister-in-law, but his knife ended up on the street and he ran as fast as he could.
The cow and her calves enjoyed the visit to the museum, and when they came back from Venezuela, we enjoyed the story she lived to tell. I'm glad the thief never found out that the cow knew nothing about karate.
