Yesterday was an exciting and eventful day for Lorena, Kelly, and Christian.  They went to camp while the workers continued working on the the house.  They had visitors and talked and emailed with lots of people about ongoing events and future plans.  I had to work a very long day.  It was very interesting work for me.  We want to make a piece of equipment that no one else really knows how to make.  We are working on the core technologies that will make it possible.  It might not be possible, so we are performing science experiments.  So, when I got home after a day of oscillating senses of frustration and satisfaction that is inherent to this kind of work, everyone wanted to talk but me.  All I wanted was to eat something and go to bed.  Nevertheless, it really was great to hear about such an eventful summer day for the family.  I think it would have been a hugely missed opportunity to not pay some attention and with a minimal amount of effort on my part, we all went to bed feeling pretty good about life.
