This is truly a lesson, honestly, fire spread more faster than we think, I remember myself in this kind of situation, I did something like this, when I was a kid, but mine wasn't in a big bush, it was in a small garden that my mother used to plants, African garden egg and tomato, yet before I knew it, the fire get into someone's else farm, that was close to us.
And the owner of the farm came the next day and was angry, I was beaten by my mother, for bringing troubles to her.
In your case, maybe the reason your father could not get angry with you, was because he sees you were becoming a fire man, he fear you might used your fire on him.
So he was avoiding your troubles.
