I know that a lot of people would rather be at home. That's quite understandable, and I agree with you, but it's horrid missing home and feeling miserable all the time.
I'm Arcturus Black, and I'm a wizard from Britain. If you're fourteen or younger, this is your official invitation to join me for a day of adventure tomorrow. Exploring the woods looking for creatures, going boating, having a snow war, and other such things. You can have lunch at mine if you like. The elves'll make it, and we'll have a proper feast.
Wizards especially welcome - that means you, Malfoy!
No girls who are going to cry and make a fuss if they're hit by a snowball, or who might be scared of creatures. Sensible girls can join us. No infants.
If you're not a wizard you can still come as long as you don't hate magic or think it's evil and you're going to listen to me so you don't accidentally get hurt. That goes for everyone. I'm in charge. But it'll be fun.
