You are in 4 year of hogwarts, on (your choice) house. You never really got along with the potion teacher, Severus Snape, as you gave up trying to please him a long time ago, not wanting to waste any more time trying.

Walking around Hogwarts, you see Snape in the distance, collecting a plant for his potions, but with some difficulty due to the cold and his little tolerance for this, his hands shaking even with gloves.
