Ooh!! I know, I know!!! Actually, I cheated and googled just out of curiousity, and was bullied into posting a new one since I knew.
This one was
Revolving Revelations by Paul-Gabriel Wiener, which I had to read, since I hadn't. Very cute story and not too long... so go read it!!!
So here's the new one:
"Clark!" she screeched.
"Lois, I can explain-" he began, not really all that aware
of what he was saying.
"You can - you can explain? You just waltz in from the
*ceiling*, and you can *explain*?"
"It's not like it looks," he said lamely.
Good luck!
