Maybe you could play cards? We have some fun card games that are easy for one or two people to play. Do you like word games? I have one called bannanagrams, that you can play alone too. My girlfriend has a serious soduku problem, but I don't like numbers.
I also just took up crocheting again after like 15 years. It's fast & easy & fun - plus you can make christmas presents! I'm 1/3 of the way through scarf #2 in just two weeks!
