Pleasure need not be expensive, here are some free and cheap ideas for you to enjoy.
Make some home made fudge and enjoy with a cup of tea and a good (library) book.
Spend an evening making homemade bird treats - for example coat a pine cone with peanut butter and then cover in wild bird seed or string peanuts in their shells for tasty winter treats.
Wrap up warm and go for a long walk in the park or countryside or the beach...dog optional! Take a thermos of coffee or soup.
Visit your parents or grandparents - you will give a lot of pleasure to them and have happy memories yourself.
Do a jigsaw.
Watch a favourite film. (dvds can be hired inexpensively from the library or record off the tv)
Watch tv on your pc with sites such as http://www.bbc.co.uk/iplayer/
Go for a cycle ride.
Do some charity work.
Go for a walk along the canal or river and feed the ducks (not bread)A good feed supplier should be able to sell you some duck food. Or the RSPCA do a special wildfowl (duck and swan ) food http://www.birdfood.co.uk/products.php?area_id =2&nav_id=24
Go and forage for some free food. Get a good library book on the subject to help, otherwise stick to things you are sure you recognise such as blackberries in autumn.
Visit a museum or hall and go for a walk in the grounds also.
Playing cards or any boardgame.
