"Manhattan. You could have just asked." Something about the way she explained her observations calmed him a little. It made him reflect on something she'd told him earlier. That she was a terrible people person. At the time he saw little in the way of actual justification. But now he could see why that might be the case. With a sigh, he shook his head and relaxed. Using the next few seconds to focus on preparing his coffee the way he liked it. Milk and two sugars. Since the biscuits seemed like they existed purely for the sake of adding texture to meals, he resorted to dipping them in his coffee before actually trying to eat them. And surprisingly this did actually help a fair bit.
Feeling satisfied that he wasn't going to end up drinking bitter water and dry cardboard, he looked back at her. "Is that it? I figured you'd be more observant. Maybe figure out a few personal details along the way. The kinds of things people won't readily admit to." Since he was more or less over her poor communication about how she'd been figuring him out, he posed that question sarcastically. But he did actually want to know if there was more, despite the fact he was joking with her.
