she came knocking on my door last week!! it was about 6.30pm. i'm in nunhead- the queens road end. she said she needed ?7 to charge her electricity meter key as she was completely out of power. she was crying and i probably would have fallen for it but my husband was in and he's a lot more cynical than me! she said that she couldn't even heat her baby's bottle so he'd missed a feed - i told her to bring the bottle and i'd warm it up for her. and surprise surprise she didn't come back!!
