Honestly she had sort of been hoping he'd maybe at the most wave and then ignore her. Go back to reading...whatever it was that he was reading. The last thing she needed was to be staring at the face of someone she knew to be trapped in hell. "Hi." she said awkwardly, and then shook her head. "No, just came for..." she blinked at his joke, and arched an eyebrow before reaching for a cup on the shelf. "coffee. I just came for coffee."
And she honestly wasn't hungry. She also got that Booth was just trying to be friendly. But he didn't know, and didn't understand that history that came attached with the face he was wearing. At least what it meant for her. She as worried about Angel and pissed at him all at the same time. Listening to bag egg jokes didn't make it easier. She'd get over it eventually, she knew that. Buffy would get over it, but not right away, not this second. She was only human.
Especially right now. No slayer powers or duties, she was free to be human. And this human as not in the mood. Glancing over her shoulder for a moment, she went about pulling down the coffee grounds, and filling up the coffee maker. Buffy would have to head out shopping soon and restock her kitchen.
