He wrote: "Eventually Con touched on an unusual yet memorable topic about the inevitability of our deaths and maybe because I’m older than her she asked if I feared my death in the same way she did.
"Con waited anxiously yet patiently as I carefully collected the correct words to accompany my feelings, eventually I answered that because of her, I felt no fear whatsoever because I had gotten to experience the kind of real profound love that only she could provide I felt so grateful that I could die in that moment completely content and without fear.
"Luckily for me Con thought this was one of my most romantic moments and it was as effortless as telling the truth always should be.
"This is the part where I say one thing led to another and we end up entangled like copulating snakes on the side of the road.
"It’s probably also worth a mention that I’m in no hurry to fix the stereo and am eagerly anticipating our next road trip."
