Kurt always checked to see if the loft door was unlocked before he went inside. He didn't even have to reach for his keys, as this time, the door slid right open. He sighed. "Blaine, how many times do I have to tell you that if you don't lock that door, we're going to get…" The words were stolen right out of his mouth by the sight in front of him: Blaine was dancing around the apartment in his boxer shorts and a tank top, using a broom as a microphone stand. Kurt tried to laugh as quietly as possible, but he eventually burst out laughing, breaking Blaine's concentration.
"Kurt, you're early!" Blaine said. His cheeks were blushing as red as tomatoes.
"My class got cancelled," he said, still trying to control his laughter. "What are you up to?" asked Kurt.
"I'm cleaning the loft, if you must know," Blaine replied.
Kurt looked around. The place was absolutely spotless.
"I just have the bathroom left to do," Blaine continued.
"Does that mean you're going to dance for me?" Kurt asked, laughing again.
"Absolutely not. That is my private cleaning ritual," Blaine said.
"Fine," Kurt said. "I'm going to get started on dinner." As Kurt began cooking, he repeatedly made fun of Blaine's silly dancing. Kurt teased him for days to come.
