AN: This was based of the prompt: 'That awkward moment when you realize you're in love with you best friend's girl...again' from the drabble meme on LJ.
This one is angsty!
Puck has lived through many moments during his life. The moment he slept with his best friend's girlfriend, the moment he found out he knocked her up, the moment Quinn decided to give his daughter way, the moment he decided to drive his mom's Volvo into a convenient story and try to take off with the ATM, the moment New Directions won Nationals (this is actually one of his favorites), the moment he graduated from high school (by some miracle), the moment he finished his first song. He will admit that his life has been made up of a bunch of moments both good and bad and he wonders why all of them have led him here, to a new moment that feels oddly familiar.
Because across the room there is this tiny brunette who is bouncing around from person to person making sure that everyone in the room is happy. She's a great hostess and he tries for a moment to tear his eyes away from her smile, but he fails and she's caught him looking in her direction and she's making her way over. This is one of those moments he wished he had the ability to just become invisible. Finn stops her when she's about half way there and she turns around and heads towards the kitchen holding on to Finn's arm and Puck's pretty sure he just dodged a bullet.
This thing he's feeling, it's the reason he doesn't become friends with women. Because when you become friends and they talk to you and they open up and you realize that you understand her pretty well (maybe even more than her boyfriend ever will) and she actually listens when you talk (you've been uncharacteristically honest with her for a long time).
She had called him the last time they got into a big fight and broke up for all of twelve hours. Watching them talk to Mike and Tina, he wonders how many times they've actually broken up for tiny moments of time. He wonders what he says to her that makes her say it's over and then wonders if there is ever a time that she actually means it but goes back because she's comfortable, or because she thinks that what she has is how it's supposed to be.
So all those friendship moments he's experienced lately, lead him to one more of those moments that he will use to define his life. It will be one of those moments that he will touch on vaguely in his autobiography and change all the names for the protection of…well himself. Because as Rachel approaches him and asks him if he's enjoying himself at the party she's throwing for Carole and Burt's ten year wedding anniversary. He says that he is even though he could think of a few things that would be less torturous. And when Santana calls her name she excuses herself and turns to walk away, the moment happens. It's that awkward moment when you realize you're in love with your best friend's girl…again. And there isn't anything you can do about it, and you won't.
