My mum uses this saying the most, especially to call a derailing child back to order.

You don't stop a child from growing a long tooth so far he has big lips to cover it .

He who argues with a king will only be on his knees for long.

It's only a wise leper that doesn't get killed in a foretold war.
Hope you like my entry.
