These two are definitely not #SiblingGoals.

To promote their upcoming film Cake, Sanam Saeed and Aamina Sheikh share some good-natured banter on Twitter, and we've got to say, it's quite relatable.

It started with a video message from Zareen (Sheikh) to Zara (Saeed) wishing her a belated birthday. "I'm a little late but I didn't forget. Happy Birthday. For the past few days mom has been all about you, Zara ki birthday hai, Zara ki birthday hai... I hope you had a good time. Call me whenever you find the time, it's been a while," she wrote.

Sanam didn't buy it, of course. "Yes #zareen I’m the one who doesn’t call! Pfff! Thanks for finally remembering... wow, can’t believe you wished me so late. I bet you had totally forgotten about my birthday, just like you always do!"

And then writing this gem:"Thora smile bhi kar sakti ho once in a while btw."

Of course, Zareen wasn't going to let Zara have the last word. "Aj itna time kaisay mil gaya tumhain itna tweet karnay ka? No work? Family kaisay radar par agayi tumharay aik dum se?"

But Zara's not holding back either. "Umm... #zareen I don’t appreciate you lecturing me when you don’t know half the story. Meray pass kitna time hai ya nahi shouldn’t always be your concern."

Older sister coming to the rescue, but...

... Zara's still not having it.

"Seriously? Tell you my half of the story? Main kioon gai London in the first place? Are we really going there!? What’s your issue bhai!? You know what forget it... I can’t believe you!"

If you're on edge, so are we.
