How do you define PLAYING?

I have not yet finished reading all 3 books, but I am reading them whenever I have a chance to. Could you post a few examples of what some members are doing for PLAYING and what their Friday-Nite Essence is for them? I am a grandma with 15 grandchildren and I try to do interactive things with them whenever I visit them. I bring books from the library and we have fun reading them together. The older ones will then read them to themselves. I also play computer games with them. What I enjoy most are challenging games where I get to solve a puzzle or figure out how to conquer the board before going to the next level games. I also enjoy watching others be successful at what they try to do. Is this the kind of direction for me to go toward?
