The lizard in the sink

When Yule went to the sink, she spotted the lizard. It was patchy off-white. Yule did not dare look at it. She screamed for her husband. "There's a lizard in the sink!"
"Is it dead?" He asked. He was still watching the television.
Yule prodded it with a chopstick. It moved lazily. Its beady black eyes appeared to be staring back at her.
"YES. Yes it is!" She said. She backed away from the sink.
"I'm going out. Get rid of it!" She said.
She left the house, not even casting a look at her husband in the living room. It was evening. She went to the supermarket and did her best to shop. The thought of the lizard clouded her mind. After buying her groceries, she called her husband.
"Have you gotten rid of it?"
"Gotten rid of what?"
"The lizard."
"Oh. I will," he said, and hung up.
She shook with anger. She wanted to go back and smash his face. It was going to rain soon, and the meats she bought would require refrigeration. She took a taxi home, fuming.
When she went in the front door, everything looked the same. The television was still on. She called for her husband. He did not respond. She thought that he must be asleep. Her arms were tired from carrying the groceries. She went to the kitchen, avoiding looking in the kitchen sink. The memory of the black eyes looking at her was still etched in her mind.
When she had put the groceries away, she looked at the sink, but did not dare approach it. She waited for a few minutes, then took a step forward, leaning in to look.
The lizard was still there. It was trying to crawl out, but it had changed. Now it had two tails. A smaller tail came out of the end behind its rear legs. Its twin tails flicked about desperately on the silver surface. Yule jumped back. Wanting to scream.
She went to the living room. Her husband was not there. She did not feel like eating. She tried to watch television but the thought of the lizard flooded her mind. The rain was starting to come down heavily, washing against the windows. The thought of the lizard scampering again and again on the smooth aluminum sides of the sink flooded her brain.
Eventually she fell asleep without changing out of her clothes. When she awoke, she thought she heard a thudding sound again and again. She looked for her husband; he was not there. She realised it was coming from the kitchen. Was it an intruder? Had someone come in? She took a paperweight and moved slowly towards the door. She pushed it open, and turned on the lights. The thudding sound was coming from the sink.
I need to know, she said.
She looked into the sink. The lizard was still there, but now it had a multitude of tails; four or five of them, all flicking about desperately. She screamed, and bought the paperweight down on the lizard. She crushed it again and again. Grey blood seeped from the wounds, but the tails of the dying creature continued to flick desperately.
Her husband woke up from her screaming. He rushed down. She was crouched on the floor, the paperweight on the ground. Two tails still clung onto it, desperately swinging around. Tears emerged from her eyes.
Her husband pulled her away, then used a plastic bag to remove the remnants of the lizard.
"Why did you wait so long?" she screamed. "Why?"
Her husband could not respond. Through the translucent skin of the bag he could still see the desperately flicking tails.
