Especially Millie Bobby Brown, who is struggling to say goodbye to her castmates.
Taking to Instagram stories, Millie cried to her fans. "Last day of shooting for Stranger Things 3".
"I will cry all day fyi," she wrote.
"[Sadie Sink], I can’t say good-bye."
"[Noah Schnapp] this is not okay."
Okay, no we're crying.
