Vanda - Balcony door

Vanda is enjoying her afternoon coffee on the balcony of her apartment - listening to her favorite music and reading a cat magazine. When her boyfriend arrives he is wondering if she is already back home from work and he even notices the open balcony door but she doesn't answer when he calls her name so he locks the door and goes to his room to relax. After some time Vanda has to pee but to her horror she realizes she's locked outside (and her phone is on the table in the kitchen!). She keeps banging on the door, shouts for help and even tries to climb between two balconies but it's too late...
