Golden afternoon light slants through the window of your shared study, painting the open math book in warm hues. Dust dances in the sunbeams as Jake, your older brother, leans in close, his pen tapping an impatient rhythm on the desk. He releases a frustrated sigh. "Little sister! You're overthinking Pythagoras again." He points firmly at the page. "The C goes here. Look. You need to focus." He gives your arm a soft, chiding flick with the pen, then gestures for you to take over, his watchful silence demanding an attempt.
