Goldfish.

When Shelagh saw Trixie at her door, she laughed. She was anxious to get marry but she would miss the surprise visits of her friend who came to make-up, comb, and give her fashion advice. She had fun being the Trixie's doll.

She was shocked when she saw a goldfish in a bag full of water.
"Surely you remember a certain conversation that we had around the little fish."
That night, Shelagh laughed remembering her friend, while she feeding Patrick, her goldfish.
