Pair Programming is not Optional
Pair Programming is one of the most simple and yet harder on XP practices. It's amazing how much sense of private ownership we built before embracing XP practices, lots of folks argue that private ownership is better or fits better for they believes. For years I had this thoughts about my classes are not yours. Some mindsets are harder to get, like developer written tests, that's hard one too but I will not talk about tests today, this is another conversation :D Ownership has power and this is one of the compelling reasons what should you care about pair programming.
