Catalyst: L found a flower on the ground and put it in an open mailbox on the way home.
Story: The flower lay in the mailbox, unexposed to the elements, atop the Morgans' electricity bill. Laura and Richard came home at the same time and, as Richard parked the car, Laura would go out to the mailbox and retrieve whatever lay within.
Reaching her hand in today, she pulled out the still-crisp flower and stared at it.
"Richard!" she said, stomping into the house. "Richard, come here!"
"What?" Richard put his keys on the kitchen counter.
Laura held the flower out to him. "Someone put this in our mailbox."
"I don't know, Richard, why don't you tell me?"
"Honey, I don't know who would do that," Richard moved to her, to take the flower. "Where was it?"
"I told you it was in the mailbox!" she held it away from him. "Was it her, Richard? Was it her again?"
"Jesus, Laura," Richard said, turning away. "It's over with her. I ended it. You know that."
"Do I? Because this says different!"
"No it does--"
"She's coming back! She's putting things in our mailbox now!"
"We don't know for sure--"
"Don't be a child!" she threw the flower across the room. "Who else would it be?"
"It could by anyone!"
"Why would anyone put a flower in someone's mailbox?" Laura began to cry. "You bastard," she said, then. "You bastard."
"Who would do this to us?" Richard said to himself, under his breath. He sat at the kitchen table. "Why?"
