Read the following passage from Dragonwings by Laurence Yep.

"Know where there's a garage?" the demon finally asked.

Father only grunted. His eyes were shining. He had hardly heard the demon until the demon tapped him on the shoulder. "You sabe me? Garage. Repair my Oldsmobile." As happens sometimes between two people speaking different languages, the demon had begun to shout at Father as if Father were deaf and the demon could make his words better understood by being loud.

Based on the man’s words in this passage, the reader can conclude that

he lacks confidence in Father’s ability to fix the horseless carriage.
he has had a lot of interactions with other Chinese immigrants.
he is a cruel and heartless man who cares only about himself.
he is eager to give Father a job working in his real estate office.
