prophetic humor

Wouldn’t it have been fun if Snape and Lupin’s mutual hatred/annoyance towards Fudge and Umbridge had made them forgot their own differences and they would have become friends or at least sarcastic conversation pals?

I imagine this happening before some meeting of Order, both are early and waiting for the others. Then Sirius would come in and finds them laughing or saying something witty and Sirius would think they have gone mad and wouldn’t understand what’s going on… like I can imagine both Snape and Lupin loving puns and word plays as they both are book smart and verbal.
