[There's a wonderful smell coming from the Coolidge house. Stella's spent her morning baking a delicious cake for a very special occasion (and shooing away housemates who'd try to sneak a taste). Although the windows are closed thanks to the season, the smell should eventually sneak out of the house to make its presence known. Specifically, Stella's making this. Outside of the house and on one of the chairs on the porch is tied a soft pink balloon, which sways gently in the wind. That's the only hint she's giving as to what she's making this cake for.
Well. That, and what she writes once she's ready.]
Shirley? Would you like to come over for some time? There's something I need to show you.
