Sorry, but I cannot respond to your poll. There is at least one valid response option missing. That is, "My girlfriend and I are really stupid and both us us should seek professional help, not from a lawyer but from a mental health professional." Dude, you weren't thinking during the incident and you remain incapable of rational thought if you can't look back and see, regardless of the driver's initial behavior, both you and your girlfriend far exceeded the driver in the "Duh!" factor.
Think, next time. Even better, start now. It's still not too late. And about those anger management classes....
