The Last Snow

A young boy named Bobby Muir is playing in the snow, when he sees a strange sight. (image is 'Tales From The Loop ', by Simon Stålenhag)

Little Bobby Muir was knee-deep in snow, as he put the finishing touches to his snow goblin. He wasn't tall enough to make a snowman, so he settled on a snow goblin, with an old bent carrot as the nose.
He was 8 years old, and had seen only a few snowy days in his time. He lived in a hot country (he couldn't pronounce the name) and so always valued the days of snow when they came around. His father was in the army, and his mother was in the house, detesting the cold.
So Bobby played alone in the snow, building his snow goblin... until he felt the ground shaking underneath him. He enjoyed the funny wobbling feeling it gave him, and then he saw what was causing the shaking.
On the road in front of him were hulking silver shapes, like big animals, crushing their way through the freshly fallen snow. They were funny looking, but scary. Big round things, with long tubes at the front, weird wheels with tracks on them. They looked a little like ant-eaters, but rounder, and shinier. On their orb-like bodies there was a big yellow-black shape, like three triangles around a circle. Bobby recognised it, but didn't know what it meant.
Bobby then remembered his father told him about these things, but he didn't say what they were. And here they were, in front of him! Bobby could hardly believe his luck, no doubt his father was with them!
But soon the metal things had vanished, going towards the horizon. Bobby heard his mother call something to him from the house, and got up to go back to her.
As he returned to the house, the ground shook again, but this time only once, and harder than before. In the distance, a black cloud of smoke soared towards the sky, looking a lot like a mushroom. Bobby could then hear rumblings and booming sounds coming from the direction the silver things had gone to.
Little Bobby Muir would have another many more winters, but he would never have another snow.
