you already have a computer. that should cover you. its got all the games you coul want. covers reading because you library should have a web site, socializing the is EP and many others. paint programs, builing programs etc etc etc
some times its more fun not having a car you get to go outside and play in the snow, shoot hoops, jog, thats fun to me
some computer games??
surf for ****?
cards? find a hobby or craft to do that you'd enjoy like reading or making blankets or something....
what kinds of things do you enjoy doing?
Build models, knit or crochet or quilt?
There are blankets relatively easy to make where you take 2 layers of fleece (doesn't require sewing) and you cut strips into the edges and knot them together
then im cheap
