Here's a thing.

Ask any child what noise a train makes and they'll probably say "chugga chugga choo choo."

Funny thing is that pretty much no one alive today was around in the days when trains - powered by steam - made that sound.

The stories we're told are powerful, often even more powerful than the evidence of our senses. We think trains sound like that cos we're told they sound like that.

Stories are powerful; be careful with the stories you tell.
