Orla and the Open Door

Where Duet was choosy, her neighbour Orla was the most welcoming firefly on the whole circuit.

Orla also had two friends coming in on two wires — a left and a right. But Orla’s rule was the opposite kind of generous: if EITHER friend was on, Orla glowed. Left one on? She shone. Right one on? She shone. Both on? She shone even more happily. The only time in the whole world that Orla went dark was the lonely moment when both her friends were off at once — and even then she seemed to be listening, ready to light the instant anyone came back.

“Doesn’t it bother you,” a fussy moth asked, “that you can’t tell WHICH friend turned you on? Duet at least knows it’s both.”

“Why would that bother me?” said Orla, glowing warmly. “I’m not a counter. I’m a door. And a door’s job is to be open if anyone needs to come through. Left friend, right friend — I don’t care who knocks. If even one of them is here, that’s reason enough to shine.”

Her gift showed itself on the night of the long storm. The village had two lookout lamps — one on the north hill, one on the south — and a warning bell that was supposed to ring if any lamp lit, because a single lamp meant a single scout had spotted trouble. They’d wired the bell to Orla.

The wind knocked out the south lamp early. A pickier firefly might have sulked — only one lamp, not the proper pair. But Orla wasn’t picky. The north lamp flared, its single light poured down her left wire, and Orla lit up at once and rang the bell. One scout was enough. The village woke, and was safe, on the strength of a single light that Orla was perfectly happy to honour.

“You’d have rung it for the south one just the same,” the moth realised.

“Of course,” said Orla. “Or for both. It was never about which one. It was about whether anyone at all was calling.” She glowed, easy and open. “Duet waits for both because some things need to be doubly sure. I light for either, because some things just need someone. The circuit needs both kinds of us.”

When you wire an OR gate, you are being Orla: the output glows if EITHER input is on — one is plenty; only all-quiet leaves her dark.
