Elsa drank too much that night because she was angry with Peter. He cheated on her and broke off their engagement. Elsa talked about this with her friend Samantha while drinking at a bar. Samantha told Elsa not to drink too much but Elsa didn't listen.
Elsa and Samantha drove back home and since they were roommates, they entered their apartment on the fourth floor of a building with 9 floors.
Elsa was unstable because of all that alcohol she drank, but Samantha was a good friend and didn't let her friend walk around drunk. She brought her home safe and sound.
In the middle of the night, Samantha who was fast sleep suddenly woke up because she heard crying of a woman in the living room. She went to see what is going on and saw Elsa crying. She was sleep walking.
She woke her up and told her she shouldn't have drank too much alcohol and she should forget about her ex-finance Peter because a cheater is not someone whom you cry your eyes out for. You forgive and you forget.
Samantha was worried about Elsa and told her sleep walking is caused by drinking too much alcohol. What if she hurt herself and Samantha is not there to give her a hand and help her get up. Elsa should learn to take care of herseldf.
