Katie was on her way to Gabe's party, but her Southern upbringing (and subsequent portrayal of said upbringing) wouldn't let her show up empty-handed. Sweet little Katie wasn't the type to indulge in any underage drinking herself, which meant suckering some older man into buying it for her was a waste of time. That left various snacks, and Katie was loaded down with a basket containing a veggie and dip platter, a few bottles of assorted juices (for mixers, at the very least), and was only in need of a bag of chips or two to round out her offerings (the brownies she'd baked were in the car.)
She rounded the corner at a good clip, in a hurry to grab what she needed and be on her way (she still had to get ready, after all), and found herself rebounding off someone who'd been standing in the aisle. "Oh, shoot," she exclaimed ruefully, Georgia accent a little faded over the last two years but still prevalent. "I'm so sorry; I wasn't even paying attention."
