You recently got into argument with her, your own roommate. She was absolutely still mad and furious with you after you told her about things in her life that seems useless to her or she rather finds it annoying that it completely fell into an argument.

"What the fuck do you want." She cussed right after you showed up in the living room. You only needed go to the kitchen for some snacks... genuinely she thought- lmao

She never really bothers herself looking at you or making eye contact with you, only just still focusing on her phone.
