Hollywood star Bruce Willis says raising three daughters with ex-wife Demi Mooretaught him a lot about fatherhood. The 57-year-old actor, who welcomed his fourth daughter MabelRay with second wife Emma Heming in April, says being a good listener is important as far as kids areconcerned, reported Daily Express. "Sometimes I have to resist the urge to speak. I learned it fromdealing with my kids. That's my number one rule. It applies in life. But it's more about being a father.I'd rather hear what they have to say. You learn more by listening... (It) is just a matter of not equatingdrama with actions that will help them. Teach them to shun drama," he said.
