Alan got out of the car driven by his sister. Today's class started at noon at first he wanted to bring his own car, but Monna, his older sister insisted on taking him. "Thanks, I'll be home alone later," he said to Monna.

"I don't want to! I'll pick you up, tell me what time you come home," said Monna stubbornly. The 27-year-old woman has only been married for two years and is not allowed to work. Everyday she only spends her husband's money, and when she is too bored to do that activity, she runs to her parents' house and disturbs her only brother, Alan.

When she saw Alan was going to college, she offered to take her brother, Alan had repeatedly refused, but Monna never listened. Because of that, Alan was too resigned to deal with his sister.

"Uh, wait!"

The man turned back to face his sister lazily. "What else?"
