Susan was, in a spectacularly surprising and deeply suspicious turn of events, not late in getting to Seamus'. She'd gone into the office to properly file some paperwork, only to discover that it had already been filed. Then she'd stopped off at the Muggle supermarket near her home to do her weekly shopping, and had managed to do it all without any incident. She went home to a house that was already clean thanks to her housekeeper, and at a loss at what to do, had a two hour bath, read, and made brownies so chocolatey that they were illegal in twenty-four countries.
Thus it was a supremely relaxed but also suspicious Susan who knocked on the door to the flat. "Hi Charming," she said, leaning forward to kiss him on both cheeks, before depositing the plate of brownies in his hands, and slapping him in the rear almost absentmindedly.
