My wife, there's certain kinds of housework that she just doesn't see as necessary to do in the way that I do. Things like the state of our closet or where things are in the kitchen. I have this almost unhealthily obsessive desire to have things in their place and she just totally doesn't. And this is a potential point of conflict, of course.

The more you're drowning in familiarity, the better the fun is. It requires less novelty to produce even more gratification. And it's something that didn't come from you. It was about the other thing - the thing you were experiencing, or the people you were with, or the mechanism you were operating, or whatever it might be.

You can experience play at work, not because you're messing around or wasting time or something, but because you're looking really deeply and seriously at things and asking what is possible, what can be done with them, what new ideas might emerge?

Today, all our wives and husbands have Blackberries or iPhones or Android devices or whatever-the progeny of those original 950 and 957 models that put data in our pockets. Now we all check their email (or Twitter, or Facebook, or Instagram, or) compulsively at the dinner table, or the traffic light. Now we all stow our devices on the nightstand before bed, and check them first thing in the morning. We all do. It's not abnormal, and it's not just for business. It's just what people do. Like smoking in 1965, it's just life.

If you think of play as being in things, there are things that are playable, then it becomes the work of figuring out what a thing can do.

We don't like to think of ourselves as subject to the forces of the world, we like to think of ourselves as exerting that force.

The idea of thinking of our relationships with people as also being structured by limitations and constraints can be useful.
