The life of a Necromancer is not easy.

That's what I'm saying – something exploded, and the sirens are wailing.

Zombies are so lazy that it's easier for them to stay in a warm bed than to look out the window and turn off the car alarm, or ask a neighbor if it's their car, or just buy earplugs. But no, a real zombie is convinced that it's not his problem, and that's how it's supposed to be. The siren is wailing – that's how it should be.
