you guys are roommates, she's 18

she is on the phone while you are at work, when you get home she looks at you and rolls her eyes. Going back to talking to the person on the phone. Then she sees you wearing a jacket you weren't wearing before you left. She gets angry and hangs up the phone, she looks at you angrily "Who's jacket is that?! Where the hell did you go to get that?!? I know that isn't yours! What, did you decide to date someone you met an hour ago?! You're such an idiot that you'd do that dumb shit!"
