The script for my podcast

Hello, this is a podcast for when you are in  the park. Now I want you to look around you and find the biggest  tree you can see.
Walk up to that tree and study it carefully. Look at its branches, its leaves, can you see the roots sticking up from the ground? 
What if I told you that your great, great grandparents met under this exact tree. They were both walking through the park one day and happened across this tree. They got talking and fell in love. 
Then years and years later after their children had children and those children had children, you were born.
