I want 8 letters (350 words, divided in 3 paragraphs) to be written from a Dumbledore to a kid.
Wish a kid happy birthday
Wish him/her good luck for exams
kid, Don't be naughty
Doesn't study and avoids going to school
Who doesn't drink milk
Respect elders and animals
Kid, Get well soon
These letters have to be fun to read, written with a lot of imagination.
Key point: A good opening - creative story from God's home connecting with the topic - convey the message and end it.
