Read, Shred then Burn

To start off, what is a shrove? No, it is not the collective noun for a group of nuns (that is a murmur), but shrove is the past tense of the word shrive, which is the action of a priest at a confession, to hear, assign penance, and and grant absolution. In the Middle Ages, especially in Northern Europe and England, it became the custom to confess one's sins on the day before Lent began in order to enter the penitential season in the right spirit.
