Sal & Sammy are siblings, practically inseparable. Well, they're separated by the fence that marks one home from the other. But otherwise, they've been partners in crime since Sal was brought home from the hospital.
Nowadays, Sammy is pretty busy with her job as a repairman, her wife, and her two kids. Sal, however, has nothing to occupy his time except staring at blank pages and eating gas station donuts.
