Unfortunately in London there are a disproportionate number of the 'needy' some become needy through no fault of their own and some fall into the category through drink and/or drugs. There are also 'chancers' who will use any sob story to extract your hard earned cash, and there are perfectly capable human beings with a victim mentality who think the rest of the world owes them a living. As the years advance (and the population increases) I am increasingly suspicious of people I don't know and act accordingly and would never judge anyone who 'turns a blind eye'
