In Susan's experience there were quite a lot of thing that most people couldn't see and, usually, it was for lack of trying. She didn't say as much, though, because she'd already seemed to have ruffled his feathers a bit. Metaphorically speaking.

"I wasn't aware that being an angel and being a muse were mutually exclusive," Susan replied evenly. After all, both professions required similar dress...or lack thereof, depending on how you felt about togas. "But, I didn't know that Mythical messengers could retire, either, so I'll take your word on it."

Susan adjusted her hold on her beer and shot him some approximation of an apologetic look.

"I hope you'll excuse me catching you out like this. I was told there were other non-humans but you're the first I've actually come across in the flesh--As it were."

There was something off about his physical form, but it was hard to put her finger on. However, considering that all the angels she'd ever met were formed by pure Belief and, thus, varied wildly in everything from size to voice to construction, being just a little off meant he was closer to Normal than most. Close to Normal was the highest praise Susan could think of, so she let it pass for now.

"Honestly, I was expecting to find a lot of Tooth Faries, or something. Finding someone Religious, well--I had to ask."
