Sometimes it is the little things in life that can make a big difference.
Have you ever stopped to think about what happens to the socks that get hired out with kilts at shops across the city? No, neither had I.
But city centre beat officer PC Liam Coleman did. Wat he discovered led to an idea that will help keep homeless people warm in the Capital this winter.
All it took was a little care and lateral thinking, and the results will be lifechanging. PC Coleman expects to be dishing out dozens of pairs of donated socks to people on the streets in a move which will save some of them from suffering frostbite or worse.
Social problems which loom large in the city as winter approaches can often seem insurmountable. Those whose lives are blighted by homelessness or poverty often feel trapped and despair. Those of us who would like to help can feel that it is hopeless and there is little that we can do that will make a real difference.
John Bird, the social entrepreneur who started the Big Issue, says that the barriers created by poverty can only be pulled down one bit at a time. His point, I think, is that there is no single, easy solution, but there are lots of seemingly small things we can do which still make a difference.
