Dear Ms Parkinson:

I know you don't like me a great deal; the feeling has generally been mutual.

However...

I greatly respect your skills in your chosen field. And I am in a position where I am in need of business advice and possibly capital; my goal is to purchase (or rent) and restore The Three Broomsticks in Hogsmeade and return it to a working state as soon as possible provided any heirs of Madame Rosmerta's agree.

What would you consider a fair trade for the same? I am willing to offer anything reasonable.

Sincerely--

Lavender Brown
