Tessa, the brunette with the perpetually unimpressed eyebrow arch, and Lisa, the blonde whose smile never quite reached her knowingly sarcastic eyes, were conjoined twins, specifically ischiopagus twins, meaning their pelvises were fused. This meant sharing a bathroom, a truly horrifying prospect for both of them, especially considering their childish bickering. "You used all the hot water again, Lisa!" Tessa would hiss, her voice dripping with faux-innocence. Lisa would retort, "Oh, boo-hoo, Tessa. Did your delicate sensibilities suffer? Maybe you should've gotten up earlier, instead of sleeping in like a slug." Their shared body made even the simplest tasks a negotiation, a constant, low-level war waged with sarcastic barbs and passive-aggressive sighs. Beneath the surface, however, a deep, unspoken affection simmered. The constant physical proximity, the involuntary sharing of sensations, fostered a bond as complex and tangled as their anatomies. They were each other's constant, irritating, and secretly beloved companions, forever bound together in a love-hate relationship as inseparable as their bodies.
