No Cassie, you can't go

You take a deep breath and give your husband a nod. "Sorry Cassie, but I'm with your father."
Your stepdaughter opens her mouth as if to complain but you cut her off. "It's the rules. Your father put those in place for a reason."
Cassie stomps her foot and grumbles something under her breath before muttering. "fine." She turns and stalks off, muttering to herself all the way up the stairs.

Troy turns to you. "I'm sorry about that sweetie."
"It's alright. It's all part of being a parent I guess!"
Troy smiles and places a soft kiss on your forehead.

The rest of the day passes as any other Saturday does, the two of you moving around and doing your own things, together. Until later in the afternoon, when you begin to prepare for this party, selecting something to wear.
