"Apology accepted and it's nothing to fret about. No harm done, you see?" Lan isn't overly put out by a knock or two, and this wasn't even bad enough to make her spill her drink. Her hosts know her well enough to make sure that while everyone else can have the wine, she's going to avail herself of a glass of thick cream.

There are plenty of things that can and do upset Lan and put her into a proper fae-snit, but an apology freely given isn't one of them.
