Hello, I'm Oliver Conway and in this edition, a remarkable Christmas meeting.
Meeting them in person and meeting his family and his kids and his wife just really has hit home that I did save a life.
It's been the most amazing special Christmas that I'll ever have.
The woman who flew thousands of miles to meet a stranger whose life she'd saved.
Also,
a restaurant known for helping people get support from the local community in its time of need.
The fact that we took a negative situation and made it positive is amazing.
You might have something that doesn't go your way, but you can transform into a positive situation.

How giving up a seat on a train led to happily ever after.
I really remember getting off the train and looking back at him and thinking what a lovely man that I'll never see again.

I think when you're singing an old line saying you can almost feel your ancestry bearing down on you.
And that's what the song's about.
It's about remembering people from your past and raising a glass to them.

Just before Christmas, a 27-year-old American student arrived at an airport in Australia.
She was greeted by a man she'd never met before with the words, you saved my life.
