Wait until the end of classes.

When classes end you are in your office grading papers when you hear a knock on the door.

"Enter!"

The door opens a crack and Julia sticks her head inside.

"Miss Stevenson? You wanted to see us?"

"Of course, Miss Mitchell and Miss Miguel. Come in."

Julia walks in, looking nervous, followed by the taller, darker Angela, who mostly looks vacant and a little confused.

"Miss Stevenson? Are we in trouble?"

Angela's voice is a little smoky as she looks at you with her big, brown doe-eyes.
