Games to play by oneself?

jump on a trampoline. that is what i do :) you could imagine you are by yourself and.... jk... ok you could make up a game. like take a bunch of food out and eat it. i did that with my brother when we were little. we but a bunch of fruit and vegetable in our blender. it wasnt very good but it was fun making it. you could kick a ball around outisde or play with a pet if you have one.
