Trevor Dineen has a confession to make: he can get a little stuck in the past. He still watches Growing Pains. He can't let go of old letters. He regularly has dreams about his childhood. When the world seems uncertain, it can be comforting to look back at what's familiar. So today on Now or Never, we meet people re-visiting the past - not just for nostalgia's sake - but to help them move forward in the present. How reading love letters from the 1920s is helping one woman deal with heartache. Three siblings dig through all the contents of their childhood home and learn some surprising new things about their parents. And five people share the lessons they learned from their first kiss, and how it still stays with them today.
