Hi Emma - PLAN to do something with your evening that will keep your hands busy. Laugh at me if you want to, but I always found dressmaking, knitting and crocheting a brill way to keep myself out of the biscuit tin and crisp packet. Plus of course not having much spare money it also gave me nice things to wear. Or, if you can draw anything recognisable - teach yourself to watercolour paint. Or calligraphy. Or start typing a novel. Or start looking to see if anyone in your area is roughly the same age and in the same boat - get out of the house and get together.
Or anything !! LOL I admit failure though when I finally decided to read Les Miserables. Just couldn't get into the book whatsoever though I can have a damn good weep at either the musical or the film. Oooh - adult tap-dancing lessons - bloody hilarious and ace good fun - and the reason I was reminded to say that was because 'Master of the House' was one of the tunes we tapped to.
