Is there an animal saying or expression in any language you like, and does it ring true for you?

A natural way to answer

There's a saying that you can't teach an old dog new tricks. I don't fully agree with it, honestly, I think people can change at any age if they really want to.

Key phrases to use

• stir things up — cause trouble or disagreement, often deliberately“He loves to stir things up at meetings.”
• ring true — seem genuine, accurate or believable“Her excuse didn't quite ring true.”
• get a head start — begin earlier than others, gaining an advantage“Leaving early gives us a head start.”
• hit the nail on the head — describe or identify something exactly right“You've hit the nail on the head there.”
