"Cynthia, I hate to be a bother but..." She's shifting her feet nervously, as she starts blushing slightly. "I was wondering if you might be able to help me pick out an outfit to wear on a date... I do not trust memory on what colors my clothes are to not make an idiot out of myself."
"Wait, you've got a date?"
It was probably telling that that was Cynthia's first reaction to the question, looking up and at her older sister in surprise. She frowned, blinking as she tried to process that fact before shrugging.
"Well, none of my business, I guess..unless it's someone I know - wait, nevermind. Embarassing grilling of your personal life later." She clapped her hands together and shot up to her feet, beaming at her as she raised two eyebrows. "Alright, come on, let's go! No time to waste - and I suppose I probably know more about this than you do. Although maybe you shouldn't repeat how my first, uh, date went."
She'd never actually told her sister about that, and turned a vague shade of pink at the memory before waving a hand. "Right. So we'll just go to every store except *that* one in case anybody recognizes me. So...you ready to head out now?"
