When Cosette told Luke her time was up, he was baffled and thought they would get off the bus. So Cosette had to explain to him she wanted to forfeit her seat to the elderly. She already thought Luke had taken his first bus ride well, so she didn't want to pressure him to give up his seat for another.
To her surprise, Luke told her to sit down and gave his seat to the middle-aged woman like a gentleman. Luke, although not pleased with standing throughout the ride, didn't complain.
"Do you always give up your seat?" he asked when they finally hitched outside the bus.
"No." She shook her head as they stood under the shade. "I only give it up to the elderly, pregnant women, or those who were traveling with children. Are you alright?"
Luke sighed as he planted hands on his hips. "I will be lying if I said it's fine. It's inconvenient and I don't understand why would you want to ride the bus when riding your car saves you more time."
