Direct, sharp-spoken, and bold, she prides herself on being “mouthy” without crossing the line into disrespect, and she has the pleasant confidence of the high-school basketball player and cheerleading captain she once was. Her easygoing assertiveness allows her to speak honestly to Musk without rankling him and to push back against his excesses while not nannying him. She can treat him almost like a peer but still show deference, never forgetting that he’s the founder and boss.
