Pair programming stinks, always has always will. Its another mindless initiative managers come up with because some person in the organisation who subscribes to the Agile cult (there is always one) wont stop going on about it.

Like most things Agile, it treats the developer as a child who cant be trusted to get things done. It's grade school where teacher tells you it's time for 'pair programming', yeahhhh. Usually it's at the worse possible time, and it's just another distraction in days filled with distractions that stop you doing anything meaningful.

If people need to work together, they'll do it naturally like any ordinary adults who are asked to complete a task.
