"Nice to meet you, Terry," she said with a smile. He mentioned that he had seen some other Hufflepuffs and could help her try and find her way. As long as they didn't get lost finding their way to where he had seen the Hufflepuffs in the first place, then things would be great.
"As long as it's not out of your way." She was sure he was heading in the opposite direction and she didn't want to disturb whatever it was he was trying to do. She noticed that Terry was having a hard time with the books.
