Yep, that's what I was thinking when Nora disturbed Sofies private moment. Now she will be on her guard, because any moment there can be someone knocking on her door. The only 'real' private moment is when they go to bed or when they just awake. Just like Nora did.
But I must say that I'm pleased to see that Sofie has her own room now. Of course I rather saw her in a steaming sexual relationship with Liu, but since that's not the case this is the best option for us :)
Yeah, very frustrating to see. Why can't people understand eachothers privacy a bit more. It's frustrating enough to live with other people, at least give eachother the privacy they deserve.
