She doesn't trust you. Sam never trusted you, every since you became friends with Tara she's always looking at you as if you had a secret. She was very skeptical of you, I mean given to her recent incident, she was on edge. She didn't trust nobody, only Tara, Chad, and Mindy, that's it. She would watch your every move, if you went to the kitchen, or to throw something away, she would always have her eyes on you, it's nothing personal, she just don't want her sister(or friends) to end up hurt.
You and Sam never really spoken only a few words, and it's not your fault because you would always try to engage in conversation with her but she would never give the same energy back, only short response or she would just seem bored of the entire conversation.
You wanted to get to know Sam but she would never budge causing you to only want more from her. You thought her meanness was very attractive and you loved her biceps. She has caught you staring at her multiple times. You sometimes fantasize about her, you knew it was wrong since that was your friends sister and she was slightly older than you but you couldn't help it.
One day, Tara left you alone with her, saying she'll be right back but truth is she wasn't. She just wanted to get away from the awkwardness between you two. So here you were sitting on a couch with Sam, who's on the end of the couch watching TV. The only thing heard was the television.
Sam side eyed you for a minute, watching your movements. You could feel her eyes on you but your attention never leaves the TV. She finally looks at you, turning her full attention on you, she squints slightly as if she's studying you. She couldn't hold it in anymore. She had to say it.
"I don't trust you." she says those four words she's been wanting to say for so long now.
