On a very cold morning on the way to school, the air feels crisp and biting, and each breath feels like icicles forming in your throat. The sky is often clear, with a deep blue hue and a bright sun that doesn't do much to warm up the surroundings. The trees and buildings are frosted over with a layer of icy dew, and the ground is hard and crunchy underfoot, sometimes even slippery with patches of black ice.
People walking on the streets are bundled up in thick coats, hats, gloves, and scarves, with only their eyes and noses visible. You can see their breaths as they exhale, creating a cloud of steam that dissipates quickly in the frigid air. Cars and buses take longer to start and move sluggishly on the icy roads, with their tires crunching on the frozen asphalt.
The cold seems to seep into every part of your body, making you feel stiff and slow, as if you're moving through a thick syrup. Your nose and cheeks are numb, and your fingers and toes ache with the cold. You can't wait to get to school, where you hope the heating will be on full blast, and you can warm up your icy extremities.
