Castiel didn't flinch or draw back when she leaned forward. If she wanted a better look at him, then she was welcome to it. It never occurred to him that it might have been strange, but a part of him assumed that were Dean present, he would have made a comment by now. As he thought about it, the more he felt somewhat relieved that Dean wasn't. He cared a great deal for the Winchesters, but even at the best of times, he found he didn't know what to call them. "Friends" was too impersonal, but they were not family either.

They were curious by nature and often took exploratory measures when it came to anything they didn't fully understand. Just because he didn't condone it didn't mean he believed it impossible.

He'd come to learn that most alcoholic beverages had nonsensical names. "I've never had those either. But I've found both vodka and whiskey useful."
Turning to look at her, he stared blankly yet again. "I take if you've been on Earth for some time."
