Dear Mr. Black,

We have recently received word from Mr. Potter that you have arranged to be married to a Giant Squid located on Hogwarts Grounds. We have located this squid and fixed the problem. Your detention will take place at 8 o'clock this evening in my office. Bring protective gloves.

Professor Minerva McGonagal

Dear Professor McGonagal,

Minnie, before I found this note, 2 Hufflepuffs, 7 Ravenclaws, 6 Gryffindors, and 19 Slytherins had read it. Please drop my notes off at my dorm next time, Kay? I only just managed to stop Snivellus from reading this to the entire school.

Love, Siriu
