Foreshadowing

It's almost dark as I ride the train home this evening.  It's not late.  Only just after 6:30.  But with the overcast weather it seems much later.  It also makes me begin to dread what will happen when the time changes next month.  It will be dark in the morning when I go to work (it already is) and dark when I arrive home.  When that happens, I'll have to make a special effort to see the sun sometime during my workday.  And if I don't, at least maybe the darkness will help me in my quest to perfect sleeping on the train.
