['My best friend is finally able to come back to school after an academic suspension.', "That's good!  Was there a reason for the suspension?", "She had failed too many classes.  We're in the same classes this semester, so that should help keep her on track."]
It'll be good for her to have your support, so hopefully she'll do better this semester.
My best friend is returning to college after an academic suspension.  I hope that this semester will be different since I'm taking the same classes as her.
