"Dirk was running late for his job interview, but it didn't matter because he knew he would get the job. He had felt that way about the previous jobs he had applied for, but he was still
unemployed. He wasn't too worried about leaving the house late because he was such a
great driver he would be able to make the time up. Unfortunately, his unparalleled driving
skills did not prevent him from getting stuck in traffic and he pulled into the parking lot late.
He found a parking space up front, but someone had gotten there first and was trying to
pull in as he cut them off. The driver of the other car honked and drove away as Dirk
laughed at their incompetence. Dirk was relieved to hear that his interviewer was running
late, but panicked when the driver of the car Dirk had cut off in the parking lot introduced
himself as his interviewer."

The world is all about determination

a complex sentence consists of an independent clause and one or more dependent clauses.  

to write complex sentences, we must use subordinating conjunctions.  

all the complex sentences begin with a subordinating conjunction and when it occurs, a comma must be place at the end of the dependent clause. on the contrary, if the sentence begins with an independent clause, then no comma is used.
