Let's imagine this:

You're 15, and you're dad is never home. Your birthday, your graduation, etcetera because he is touring to please some assholes in a fan board.

With time maybe his family got sick with this. That justify his trip with his daughter to Europe, maybe it was planed way before since they're suppoused to be doing a break. Then, your "boss" call you up one day and says he's tired of his vacation in Bahamas and he'd releasing another record/tour.

Honestly, if I was him, after 30 years touring, I'd tell my boss to suck my dick. But hey, if I was his son, I would do the same.
