Ravenclaws are extremely interesting

We’ll start off with the most obvious reason to befriend a Ravenclaw – they’re smart. And we’re not just saying that’s a good thing because they’ll be able to help you do your tax return.

Ravenclaws are curious about the world, which makes for fascinating company. They’ll always be able to let you know about a great new book they’ve read, or fill you in on current events, or be so witty they’ll make you look great if you bring them as your plus-one to a wedding reception.

Basically, you’ll never be stuck talking about the weather with a Ravenclaw. Your friendship is likely to be based on deeper, more philosophical conversations – rather than ‘How was your weekend?’

‘I don’t think you should be an Auror, Harry,’ said Luna unexpectedly. Everybody looked at her. ‘The Aurors are part of the Rotfang Conspiracy, I thought everyone knew that. They’re working to bring down the Ministry of Magic from within using a mixture of dark magic and gum disease.’

You will never doubt how much you matter to a Ravenclaw

Ravenclaws are logical and rational and will always have an argument to hand when it comes to backing up their friends.

Take Cho Chang and her fellow Ravenclaw friend Marietta Edgecombe. In Order of the Phoenix, Marietta betrayed Dumbledore’s Army – and henceforth broke out in boils that spelt out the word ‘SNEAK’.

Cho instantly stuck up for her. This was pretty gutsy considering that Cho had recently lost her boyfriend Cedric Diggory to Lord Voldemort, the exact force that Dumbledore’s Army were trying to fight against. Yet she still stuck up for the person who betrayed them. Siding with Marietta also hammered the final nail in the coffin for her and Harry’s not-quite relationship, but to be honest, the writing was already on the wall that they probably weren’t meant to be.

Despite that, and losing her credibility in the D.A., Cho cared enough to defend her mate.

‘She’s a lovely person really,’ said Cho. ‘She just made a mistake –’
Harry looked at her incredulously.
‘A lovely person who made a mistake? She sold us all out, including you!’
‘Well ... we all got away, didn’t we?’ said Cho pleadingly. ‘You know, her mum works for the Ministry, it’s really difficult for her –’

Ravenclaws can see past the surface

Ravenclaw is the house for ‘those of wit and learning’, which can lead to deep intuition in a friendship as well as, say, achieving ‘Oustanding’ in all N.E.W.T.s.

Ravenclaws pay attention to the world around them – and that also means paying attention to their friends. Not all of us wear our hearts on our sleeves, but Ravenclaws are practically Legilimens when it comes to knowing when a pal needs help. A Ravenclaw can read you like a book… even when you’re using a Polyjuice Potion and disguised as a completely different person.

‘Hello, Harry!’ she said.
‘Er — my name’s Barny,’ said Harry, flummoxed.
‘Oh, have you changed that too?’ she asked brightly.
‘How did you know — ?’
‘Oh, just your expression,’ she said.

Ravenclaws work hard on their friendships

A Ravenclaw is smart enough to know that a lasting friendship requires putting in effort – and if there’s one thing a Ravenclaw’s propensity to complete homework months in advance proves, it’s that they never shy away from putting in the hard yards.

Think about the effort that Luna Lovegood goes to, to support Ron before Gryffindor’s Quidditch match against Slytherin. If bewitching a hat into a life-size lion’s head isn’t friendship, we don’t know what is.

‘Hello,’ said a vague and dreamy voice from behind them. Harry looked up: Luna Lovegood had drifted over from the Ravenclaw table. Many people were staring at her and few were openly laughing and pointing; she had managed to procure a hat shaped like a life-size lion’s head, which was perched precariously on her head.
‘I’m supporting Gryffindor,’ said Luna, pointing unnecessarily at her hat.

Ravenclaws take friendship seriously

For Ravenclaws ‘the cleverest would always be the best’ – so sings the Sorting Hat in Goblet of Fire. But friendships are to be cherished, even more than intelligence. That’s an important lesson for anyone to learn – and given their love of learning, you can be assured that Ravenclaws know it.

‘Luna had decorated her bedroom ceiling with five beautifully painted faces: Harry, Ron, Hermione, Ginny and Neville. They were not moving as the portraits at Hogwarts moved, but there was a certain magic about them all the same: Harry thought they breathed. What appeared to be fine golden chains wove around the pictures, linking them together, but after examining them for a minute or so, Harry realized that the chains were actually one word, repeated a thousand times in golden ink: friends… friends… friends… friends…
Harry felt a great rush of affection for Luna.
