My younger sister and I go to the same school. (The classes are in person.) The problem: She copies my style! I put a lot of thought into the way I dress, and it bugs me to see a copycat come down the stairs every morning. My mom won’t get involved. Will you?  —Jilly

OF ALL THE WAYS I imagined a question about in-person learning during a pandemic would play out, none included copycat dressing. But I’m an older brother, so I get your frustration, Jilly. Look at it this way: Your younger sister admires you and may not have as much confidence in her fashion sense. Why not style her for a week? Help her come up with her own look, and she may back off yours.
