The ordinary crossing
Mara had crossed the red bridge so often that she no longer noticed its colour. It belonged to the journey, like the bend in the path or the gate that always needed lifting. Len suggested stopping below it for once. From the low bank, the bridge looked less like a shortcut and more like a promise someone had built between two trees.
The other resident
A broad shadow moved through the pool beneath the central beam. It passed slowly enough for Mara to see the shape of the bass, then vanished where the reflected bridge became darkest. Above them, footsteps crossed from one bank to the other. The walkers never looked down. Mara wondered how many times she had been one of those people while the fish continued its own quieter route.
A longer way home
They left without a dramatic encounter to report. The notebook held a sketch of the bridge from underneath and a badly drawn fish that Len insisted looked like a loaf of bread. On the return walk, Mara paused halfway across. The water below showed only sky. She waited anyway. The bridge was still a shortcut, but it no longer felt like an excuse to hurry.
