For months, a coworker had been bringing up #PairProgramming at our sprint retrospectives, so we tried it out this sprint.
So far, it is fun and also efficient/productive.
For me, it is a totally different workstyle, not so much because of the pairing itself, but because of the focussed structure that it enforces on the work day. Usually, while I had been working on one main task as well, I was always the first to jump in to help with whatever someone came up on the company Slack. Plus various chores around the house #RemoteWork.
So I was much more multi-tasked and "agile" before.
And you have to be much more strict about scheduling your day.
