Hello Amy
I'm not sure how to start this letter, but I'm Charlie, your half brother. I hope you've received the letter from you dad already or not, well you'll probably just think I'm strange!
Since I've heard about you, I've really wanted to talk to you, and well just start getting to know you! I think I should tell you some stuff about me first I guess, that way it might be easier!
Well I'm 16 (your dads already told me your 11 and just starting Hogwarts NZ!)
I also, like you, have "magical blood" as your dad likes to put it!! But I'm actually home schooled, my family weren't keen on me going to a normal school like you!
Erm, I have browny hair, and green eyes, and erm I'm quite tall I guess!!!
Erm, okay I've kind of run out of things to say so I think I'll just leave it there for now!
It would be great to hear from you, and start to get to know you and everything, but I'll understand if you need time to adjust to the idea or anything like that.
So yeah, hope to speak to you soon,
Charlie
