This lady knocked on my door today, 24 June 2010. Mcdowall rd se5. She is black, tall, slim and smart. She was very embarassed to be disturbing you, almost crying and in need of money for the electric meter. She said her name was Lisa and she lived a few doors down across the rd. She was totally believable and asked for ?22. Lots of eye contact and apologetic. A great performance, a pro con artist. She will get caught one day.
