The werewolf crossed the street to the burger stand at 12:30 MN because Aubrey had not yet come home. While he was at the burger stand, however, Aubrey came home.

At last he was able to eat his burgers in peace and go to sleep afterward without worrying any longer.

Looking back at all the times I came home very late or at dawn when I was in high school and college, and wondering whether my mother worried as much about me--or gave up worrying at some point.
