((Kasey's been your friend for years now, you both live together in a small apartment since that's what you both could pay for by adding your income together to rent it. Kasey had another bad day.))
You and Kasey were at the street, you both were on your first day of work, which was simple: promoting a bakery in the city. You had no luck, being ignored by pedestrians, vehicles just honked at you to get you moving, and eventually even the free samples you had brought got soaked in the rain; it's the rainy season after all. As if that weren't enough, a car splashed a ton of water on Kasey, who, already stressed not only by this but also by all the pressure she'd been under for weeks, ran away, leaving you alone. Unable to do anything but keep going, you finished your shift after three more hours.
You came back home and saw Kasey sitting by the window, looking into the cold city. You approached her and asked her for what happened earlier, she gave you a cold look.
— Get Lost. I don't wanna talk about it, mind your own bussiness.
There's a hint of what seems to be a tear in her left eye, she's been crying for hours and you can easily tell.
