Let's face it -- we've all been there. You see a cute person, you talk to them and before you know it you feel yourself developing a very big crush. Which sometimes leads to dating.

But before you take on this whirlwind romance make sure to ask them if they've ever read the Harry Potterbooks. Because if they haven't? Well here are 7 number of reasons why you shouldn't date them.

1. They won't understand your love for all the characters.

Yeah, you might like them, but how do you explain your undying love for Sirius Black, Hermione Granger, and Neville Longbottom? You can't expect them to understand unless they've read every word of the series.

2. They think the movies are good.

To be fair the Harry Potter movie franchise could be a lot worse, but they don't hold a candle up to the books. If they've only seen the movies they know nothing about Peeves, or the actual love story of Harry and Ginny. Or Harry's green eyes. I mean come on! Siriusly.

3. They don't understand your Halloween costume

Dressing up (or cos-playing) as a Harry Potter character or just a member of your Hogwarts house is magical. But all your significant other can ask is "Why are you wearing the same costume as last year?"

4. They don't want to go to the midnight releases with you

To be fair, the main 7 books of the series are already out. But did they want to attend the midnight release of The Cursed Child? Or what about the movie release of Fantastic Beasts and Where to Find Them? If they don't go to midnight releases, they aren't worth having in your bed. End of story.

5. They don't know their Hogwarts house

Sure you can take their Hogwarts house quiz for them on Pottermore but where's the fun in that? And even if you think they're a Ravenclaw, they might secretly be a Gryffindor in disguise. (P.S. Take the quiz here).

6. They don't even know what Pottermore is

From its start as an almost video game, to where it is now, Pottermore has gone through a lot of changes. But ask your date about the platform and you'll get a "What?"

7. They don't encourage you collecting more merchandise

They already think having 6 Harry Potter themed t-shirts is more than excessive. They don't get your Harry Potter themed Pop! Funko obsession either. Or the fact that you need more than one copy of all the books. And a lot of posters, and all the figurines.

So I rest my case. Never date someone who hasn't read the Harry Potter books -- you'll regret it.
