The most complicated thing I ' ve ever changed in my car has been a cassette tape , so I really did need my brother 's help . We went to AutoZone ( after attempting to go to the Arlington Napa , which was CLOSED when they were supposed to be OPEN ) and bought a new alternator , then spent the next several hours trying to get the old one out . Despite our best efforts , we were unsuccessful at this , so we put the car back together ( we had to pull one of the front wheels off just to get to the alternator ) .
According to the above context, answer the following question.
Why did the narrator need assistance from their brother ?


The narrator is lacking car knowledge .
