Seems like an assumption to say that &quot;time together&quot; is the key difference.  For example, at various times in my life when I&#x27;ve been jobless, I did experience similar peeks in my mood over the weekend.  But I&#x27;m a solitary person and I was not necessarily spending that much more time with others.  I would say that the difference was psychological.  On the weekend, I felt okay relaxing because I knew everyone else was and the pressure was off of me to be looking for work.  During the week, I couldn&#x27;t escape thoughts about my joblessness.  The article touches on this slightly when it characterizes the difference as being more in sync or out of sync with society.
