Millie Bobby Brown has shared a candid confession about her social life and how her career has made it difficult for her to make friends.

“I don’t have many friends, because of who I am,” she said, recalling that she and her similarly young Stranger Things co-stars completed their education through private classes on set. “I didn’t go to school, so I don’t have the best social skills when it comes to people my own age and friendships.”
