Chris looked up and almost flinched at Luna's response. Not at him being called Chrissy, although it did surprise him a bit, but at her initial reaction. Once again he had the impulse to slap himself for what he said. He shook those thoughts from his head, and took another sip of his tea as two other people entered the cafeteria, Nika, then Sam. He muttered a welcome in return to Sam's greeting before Luna explained to them about the cookies she and Silas had made for everyone. 
Chris looked up from his mug as Luna sat down at the same table he was. A bit surprising to him, but he shrugged it off, and whispered to Luna.

"Sorry about that 'greeting'. It's sort of a saying that you don't really think about" Chris muttered. Geez, now it sounded like he was trying to shrug off what he had said. He shook his head slightly before talking in a slightly louder voice.

"What do you want to talk about?"
