I'm guessing she pulled up too close to the car in front of her (as people tend to do), and the guy pulled up too close for her to back up. Is it really that hard to imagine?
This is the correct answer. Those blaming the wife should actually read the article: The incident happened at about 5.30pm on Sunday, August 21 2005 when police were called by a neighbour after hearing the defendant and his partner arguing.
People like you are why they get away with this shit. 1) He was trying to end the relationship. 2) Maybe if they started getting hit back they'd actually learn. Not that I'm saying that's a good thing, but if that's what it takes then so be it.
