Quote from Antoine de Saint-Exupéry

Quote from antuan de sent exupery

You cannot create old friends hastily. No treasure more expensive than many common memories, so many hours of serious, experienced together, so many quarrels, reconciliations, emotional outbursts. Such friendship is the fruit of long years. Planting oak, funny dream that will soon find shelter in its shade.

Antoine de Saint-Exupéry

'No treasure more expensive' :  No treasure is more expensive/valuable

'many hours of serious' :  many hours of serious relationship ?

'Planting oak, funny dream that will . . ' :  If you plant an oak, it is a strange dream that you will . .

I can't find the quote, so I'm making a guess about how it should go
