It is still just such a shock to have my son away. But I'm also very busy with classes starting and needing to move forward with Science, Technology, and Society organizing. I didn't run today because I'm running at least part of a 5K race tomorrow. I have to be home and ready to go out to a Bat Mitzvah an hour after the start time, so depending on whether it starts on time I may cut off for home before the finish. I should have ridden my bike this evening, but I just felt so tired. I hadn't taken a day off from my training in more than a week, so maybe that was what I needed.
