“Be wary of silent dogs and still waters.”
The source interviewed related his personal experiences with this particular proverb – “Growing up, I always made the wrong friends. I didn’t know they were the wrong friends, but my dad did. Because he was my dad, and he knew everything. My friends were those people who would be incredibly sweet and make easy conversation, but would be very guarded around other people about their own secrets and opinions. One day, I stumbled upon these guys talking the classroom. I was outside in the corridor, and they didn’t know that I was there and listening to them. Naturally, they were talking about me. And they said some things that I can’t repeat in front of you. Upset, I went home and complained to my dad, who told me ‘Be wary of silent dogs and still waters’ – meaning it in particular about people who don’t voice their opinions on others frankly and instead plot and scheme behind the backs of others.”
This proverb is a classic Indian warning against people who don’t talk. Indian people in general are quite talkative, never hesitating to share their opinions, even and sometimes especially when it proves to awkward or unwanted. Therefore, when people aren’t talking, it means that they must be up to something. So, when someone isn’t being obnoxiously vocal about their opinions on your personality, sever all ties with them, because they probably don’t like or care about you.
