you can't understand
Why can't you understand?
Non riesci a capire cosa sta succedendo qui?
Can't you understand what's happening here?
Non riesci a capire che potrebbe essere una messinscena?
Can't you see that this could be a setup?

Can't you understand?
E come cazzo non riesci a capire se è stato a casa o no??
And how the fuck can’t you figure out whether he was home or not??
— Loveless (2017)
But can't you understand?
