CHOO CHOO MOMMY
CHOO CHOO
shareShe turns around to say "CHOO CHOO" instead of paying attention to the road...This is how accidents happen.
shareShe pisses off a driver by being too busy turning around to play with her son. He had previously lost a child due to a reckless driver. He follows her to the playground and steals her child as 'payback' for not paying attention to the road and to get a child of his own again.
Ok I made all that up, but why does it sound like that could actually be the plot of this movie!?
