Maybe it's because the jacket has been around for a long time. It could have been through a lot of years of wear and tear, and with that comes a whole bunch of memories and experiences that make it an 'old story'.
Well, I'm not sure of the exact story. But generally, Levi's trucker jackets have a long history. They were often worn by workers like truckers. Maybe Levi's dad wore it during his travels on the road, and it became a symbol of his hard - working days, with the jacket getting worn out over time and having memories of different places and experiences sewn into it.
Well, without more context, it's hard to say precisely. It could be that the story involves how Levi's dad started his career as a trucker. Perhaps he had some interesting encounters with other truckers, like sharing tales around a campfire at a truck stop. Or it could be about how his job affected his relationship with Levi and the family, for example, being away from home for long periods.
Well, it's never explicitly stated in the story. But based on the context and his appearance, he could be around 40. He seems to have the maturity and life experiences one might have at that age.
I don't think there's a clear indication of his age. However, based on the story's setting and his family situation, he's likely in his mid to late 30s. This is just an educated guess, though.
We don't really know for sure how old the dad is. It's not a detail that's focused on in the story. But if I had to take a stab at it, I'd say he could be in his mid to late 30s.
