Hope this finds you well. I'm just writing to let you know that our first Hogsmeade weekend is Saturday 19, if you're still available.
Sincerely,
Hi Mum,
We have a Hogsmeade weekend on the 19th, so would you be able to owl me up some money? I could look in Gladrags for something nice to wear to Slug Club parties while I'm there. Have you discussed this with Dad yet?
Normally I'd ask you to meet me and we could shop together but I'm having a drink with a boy (drum roll, please) so it might be a bit awkward if you were there. I'm sure you're busy with your book anyhow. I'll take Sully Blaise with me, if he's available, and give him veto rights. Of the dress, not the boy. It's just a pint anyhow.
Off to get a book from the library before it closes. Will write more later. We had a Squib in Muggle Studies whose magic was stolen by a hug. See, it's self preservational that I'm not very physically affectionate.
