I remember being in a class in college with a guy who, on the first day, told the prof that he was going to be late every time. He didn't know how, he didn't know why, but somehow, was just always late for everything. So, naturally, I ended up having to do a group presentation with him, and yes, he was late. Of course.
Punctuality is one of those life skills that costs nothing and always pays off, but not everybody is able to figure it out. One couple might have received some good motivation to practice their punctuality, however.
