Ok, picture this:
You are driving along and and get to a junction where there is another car that is stationary and waiting to turn left at a set of traffic lights. You want to turn right using the other lane at the traffic lights so you slowly start to drive around the other car.
At the same time there is a woman standing on the pavement not paying much attention because she is looking down talking to her two children (approx. 10-11 years old). She finishes talking to her kids and walks out into the road without looking so you brake. You were only doing about 2mph but she jumps as she sees your car. You stop and she crosses about 4-5 yards in front of your bonnet.
As she walks in front of your car she continuously gives you dirty looks. Even when she has crossed the road and is walking away on the pavement she continues to look back and mouth some things and gives more dirty looks.
You wave your hand at her as if to say "go away" and then you point to your eyes as if to say "you should look where you are going".
The traffic lights are still red so you wait in the right hand lane.
You then notice the same woman has left her kids standing on the pavement, has turned back and has walked 20 yards to approach your car.
She walks into the middle of the road and comes up to your driver's side window. She then bends down, puts her head through the open window and calls you a "w*nker" inches from your face.
You tell her to get her head out of your car. She swears some more. You tell her to "f*ck off" and to get her head out of your car again.
She says "you almost knocked us over".
You tell her you saw her and stopped and that she should have looked before crossing the road.
The argument continues.
There is more swearing from both sides. Voices aren't really raised but it is not a friendly exchange, and the worse things being said are swear words.
You get bored of the exchange and ask her how she can just leave her kids standing where she can no longer see them. You tell her to go away.
You then face forward and wait for the lights to change.
She spits in your face and walks off.
What do you do?
