Some guys think life is a conflict or even a lifelong tragedy, while, it's ur attitude about ur life but not mine. U don't notice the swaying of the twigs but only the dropping of the leavs, not the glitering of the sun-shined beach but only the oil-polution and the plastic rubbish floating on the sea face, not the honey melody, flamenco dancing, giggles of the children but only the unbearable street noise, the chaos and evil in ths world.
So what I would assert is the existentialism. We were born to this world without the choice to choose our parents and neighbourhood which effect us overwhelmingly in our whole life, though, the choice to select the conviction for our being is what we surely have.

And the ending just suggests she enjoys her life and wiil just keep laughing or giggling despite the unhappy experience with the stone-like changed enraged driving instructor.
