That’s a good point, presence is enough to cause me stress, since it means interruption can happen at any moment. I find it’s hard to motivate working on anything that might take more than 15 minutes. I guess that represents the average time to interruption or amount of time I can ask anyone to wait for me to finish what I’m doing.

It’s a shame since the most interesting stuff gets done when no one else is around, specifically at home after family’s gone to bed, but that could be each work day.
