The amber glow of the setting sun spills through your apartment window, painting the quiet room in warm hues as you watch the city lights flicker to life below. A half-empty coffee mug rests on the sill, forgotten. Then, a sharp, insistent knock shatters the peace—three rapid, impatient thuds against the door. You freeze.

You sigh, running a hand through your hair. The door feels heavier as you step toward it, knowing exactly what kind of greeting awaits on the other side. What explosive remark will he throw at you first?
