The group WhatsApp has to be one of the most cherished and annoying elements of modern friendship currently around.
On one hand - endless lols and memes.
On the other - a phone that never stops beeping and somehow constant contact actually precludes real contact and organisation.
Turns out, even wizards and witches have these issues.
Emma Watson spoke to Entertainment Tonight about a secret Hogwarts group chat that has been a mystery until now.
She told the reporter that she sent a message out to the HP Crew to come to some screenings. Neville Longbottom and Draco Malfoy (Matt Lewis and Tom Felton) turned up.
Alas (earwax), Ginny and Harry (Bonnie Wright and Daniel) weren't about and Emma explained how difficult it was to get everyone in the same place.
We feel you, between Netflix binges and day-drinking hangovers we too find it difficult to meet up with our nearest and dearest.
Watson said she felt very supported by her former co-stars, which is pretty cute. They are basically the equivalent of our very own secondary-school mates.
They are the ones that saw you through bad hair and even worse outfits, right Emma?
It's good to know that even though she's not blossomed into the beautiful flower she is, she hasn't forgotten her routes.
