The only time Marash Girl ever remembers her mom chastising the kids (including Marash Girl) for running and jumping was when she had a cake baking in the oven. She wasn't concerned that her kids would fall; "Don't run! The cake will fall!" she would exclaim in a heart-wrenching voice.
Marash Girl imagines that anything as fragile as gently rising cake batter -- no matter how fool-proof the recipe -- would certainly collapse at the kind of jouncing she and her siblings would cause to the wooden floor in their wonderful old house on Lowell Avenue in Newtonville!
