Read a book, ring up some friends and go up to the golf course for a game, go for a walk around the Lakes, ring up some other friends and go to a pub for a game of darts and a pint, do some writing, ring up yet more friends and get them round for a game of cards, get some housework out of the way, head into town and grab a cuppa at my favourite cafe, invite the neighbors round and have a barbecue in the garden ... ... I could go on, but there's tons of things I fill my free time with that don't require a power supply and I'm not going to go through all of them.
