I nearly wrote a post entitled 'Love your locals' earlier this year when my local independent department store moved out of the town centre, where it had been for over a century. It wasn't closing, but it would be changing drastically, no longer a place to potter into for household products and gardening stuff at weekends, but one on a trading estate focussing solely on big-ticket items.
Now I am writing the post, because the landlord of one of my local pubs has left - I believe the pub will still be open for a while, but a change in landlord always means a big change in a pub - and the Bristol steampunk weekend, Brass Brunel, has been cancelled because of lack of support. I personally haven't lost out (ticket money was refunded for the Bristol event, and there are a couple of other very good pbs in town that I drink in) but I'm very sad because it always hurts to see people put so much effort into good things that then fail to flourish. I shouldn't be too downbeat; things that could have gone horribly are now doing okay, such as Trowbridge Town Hall becoming a local arts centre, when I'd feared it would end up converted into flats. However, I do believe people should be able to follow their dreams and it makes me sad when they flounder.
So, for once, this is a fairly serious post. Love your local events and businesses. Not everyone can afford to, and if you can't, that's fine. But if you can go to the independent card shop rather than a chain or (shudder) a supermarket to buy a birthday card, do it. Shop with your local butcher, if you're still lucky enough to have one. Spurn that international coffee chain and visit the small one that's owned and run by people who care (and don't dodge taxes). No one person can keep any business open, but all of us together can make our towns and cities more interesting and unique places, as pleasing for residents to live in as they are for tourists to visit.
Love your locals. The world becomes a greyer place without them.
ETA: Don't forget to check my page for What's on in Vintage Wiltshire (which also covers the bit of Somerset just over the border). I started it to help give local events a bit of publicity.
