"El zorro no ladra cuando quiere robar el cordero"
— Geoffrey Chaucer
Simplified Meaning:
When someone wants to do something sneaky or dishonest, they will often try to keep quiet and not draw attention to themselves. Imagine a person who wants to take something without being noticed. If they made a lot of noise or acted suspiciously, people would notice them and they would get caught. So, they act very calm and normal to avoid suspicion. In real life, think about a student who wants to copy answers during a test. If they started looking around nervously or kept talking, the teacher would likely pay extra attention to them. Instead, the student would try to blend in and act as if they were taking the test honestly, so no one notices their cheating. This advice can be used to understand why some people or situations may seem harmless on the surface. If someone is being overly quiet and careful, it might be worth paying more attention to them. Always stay alert, because people don't always show their true intentions openly.
