You know what's great about kids? They find the fun wherever they go. I could make elaborate plans to take C someplace I know he would love, but really, a trip to the playground or fresh paper on his eisel and a new box of crayons would provide just as much entertainment. Not everything has to be a big adventure, because he finds the adventure in the everyday.
Just another example of something adults can learn from kids.
It doesn't have to be complicated or expensive;
you just have to find the fun in everything you do.
