Shakespeare
Penelope had always been a very firm believer in logic and reason. As a child, chess was her favorite game, and she was a match for girls twice her age. When her acceptance letter had arrived, it had taken her quite a while to get over her skepticism about the probability of magic actually being real. However, despite this, she had always found something irresistible about the story of Romeo and Juliet. Of course, the idea of falling in love so quickly was preposterous, at best. At least, she thought so. After noticing that Penelope kept a copy of the play with her at all times, her Potions partner, Percy, slipped her a note. It read:
Did my heart love till now?
Forswear it, sight!
For I ne'er saw true beauty till this night.
Perhaps it wasn't so preposterous after all.
