Lily huffed and began to carefully write down her equations on her notepaper and groaned under her breath. Math wasn’t her thing in the least – animals, cute fuzzy things – and being perpetually grumpy without realizing it were though. If she could just not do math that would be wonderful. ”i think i did this wrong” she murmured to herself as she scratched out some of her work and re-did it.

It was bound to happen more than once. The erasing and re-writing – it was what she did with math. Dreadful as it was she knew somehow that it would be important for OWLs or just y’know for having a bank account of her own in the future.
