Classmate creates one-sided rivalry

DEAR HARRIETTE: I’m struggling with this weird competitive energy between me and one of my classmates. On the surface, we’re friendly — we study together, share notes, even joke about motivating each other. But lately, it feels like our “friendly competition” is not so friendly anymore. If I do well on an assignment, they make little comments about me being a showoff. If they do well, they rub it in like it’s a victory over me. It’s starting to make me dread group work and second- guess sharing anything.
