Thank you for your comments.

Roz, I dont tend to do this often but this took the biscuit. At which stage do we stop intervening? Next she and her mates are driving down the road and throw their half finished McDonalds shake out the window at the lady with the kids in the pram for a laugh. That lady could be you Roz.

I dont advocate taking on a mad knifeman but pointing out to someone who is littering (in front of a large amount of witnesses) that it's not on might get the to listen.

As for yesterdays lady, we shall see. The police are due to call soon and they dissaprove of threats to kill.

On the McDonalds subject, why is there so much McDonalds litter in gutters around Forest Hill, we dont even have McDonalds. Do todays yoof see Forest Hill as a good place to come to and enjoy their takeaway?
