Does exactly what it says on the tin. Some of the nonsense contained herein may be very loosely related to The Sisters of Mercy, but I wouldn't bet your PayPal account on it.

Don't worry your pretty little heads about it. Above all else, remember this: You don't have to stay forever. I will understand.
The only sweary dictionary you'll ever need.
