A lot of things bothered Noah Puckerman. Small children. Spics and Spaniards. Butch chicks.
The thing that bothered him more than any other was Rachel Berry.
It didn't bother him in the morning when he woke up and she was still there. It didn't bother him when she would use twenty words when one would suffice. The way she dressed didn't bother him. It didn't bother him that she had gotten him drunk, or that she had seduced him, or that he had let her.
When she had tapped on his window a week later, he wasn't bothered. It stopped bothering him that he cleaned pools and only cleaned pools. It didn't even bother him when he realized he liked all of those things.
What bothered him was when she wore clean white socks and one of his t-shirts. (He thought she looked sexy.) He was bothered when she moaned his name ("Noah.") over and over again. (It made him hard.) It bothered him when he saw her with Finn. (And it bothered him that he was bothered.)
When he realized he could no longer bring himself to throw a slushie in her face (That was mean.) he was silent for a week. It bothered him that he lied about how much he disliked her. (Lying was unbecoming.) It bothered him that she would sometimes leave him without saying goodbye. (A quickie in the chalkroom was always a good day.)
He sometimes thought that things that bothered him, shouldn't. When he sometimes thought about all of the things that didn't bother him, he would remember when they did. (And that bothered him.)
It bothered him because if he let everything that bothered him fade away that would mean he loved her.
Noah Puckerman does not fall in love.
