"Luna, You are being disrespectful towards Adrian. No matter how much you don't see eye to eye with them, you shouldn't do something like that to your elder. Adrian was being helpful and you give him a tip! Apologise to him," pulling her sister back, Lucas lectures her.
Lucas wouldn't mind if they are being playful and pranking each other but disrespecting one when the other was helping..... well not entirely but she shouldn't give him a tip for opening the door.
"But brother...." Lucas felt wronged. She didn't want to apologise. She was just teasing him, nothing more.
"Yes, Lucas she was just being playful. We know she isn't like that to others, she didn't need to apologise to me," surprising everyone, Adrian come forth to defend Luna."
