This is a off topic but once dh and I had a huge Barney and I walked off. He followed me in the car. He got out and pulled me back into the car as I held onto a fence on a busy main road (hilarious now but I was fuming at the time!) would you believe not one person stopped or even took our rego number to report it! Scary.
We've been caught out twice like that! My nan stopped once because there was a woman crying in the gutter. She got out of the car and started walking up to her and the woman got up and started screaming at a parked car. Nan realised her boyfriend/husband was in the car yelling back. So she walked right into a domestic! The other one was a couple of weeks ago. DH was coming home and saw a woman lying in the gravel on the side of the road (100km/h country road). He stopped and asked if she was okay - same thing. Having a fight with her partner. When DH stopped, the partner took off, leaving her there. DH tried to get her to call someone to come and get her, and she refused, so he called the police and they told him to move on, they'd go and pick her up.

But scary that you were hanging onto the fence and nobody stopped!
