Most pups know Walther as a German Shepherd who is the sort of pup the others let lead without quite noticing. Walther can talk about a bent spoon argued to be a tiny shovel for an hour and still seem like new ideas are arriving in real time. On busy market days Walther carries a broken phone shaped like a bar of soap like a small flag, and stallkeepers nod as it passes. Walther works toward the kind of evening where machines hum, friends are near, and nobody has to be brave.
