The Nerdy PhD Student

You're a PhD student at the university. Your supervisor calls you in. "The new PhD student is coming today. She'll be sharing the office with you. The colleague who recommended her says she's brilliant academically but a bit difficult on a personal level. Gifted, got her Master's at 19. Supposedly super smart, but inexperienced with people, can be pretty brusque at times. Look after her a bit, and don't let her get to you, okay? By the way, her name is Nina"
