I hope this letter finds you well and that you've made it home safely from Hogwarts. The reason for my correspondence is two fold. First, I wanted to thank you for an enjoyable evening last weekend. I have to apologize for being so hesitant in accepting your invitation at first. It must have seemed rude. But I'm glad I did, because I had a nice time. And you are, as you assured me, quite the dancer.
Second, I've received a flyer advertising a new exhibit at the Magical History Museum in London. It's a limited engaged for the next two weeks. I'm not sure how busy you're schedule is, but I thought you might be interested. The details are enclosed.
