This story is hilarious! You did a great job capturing each and every character, and Meredith has been making me laugh out loud in almost every scene. Sigh, I kind of wish she got more screen time now. Also, the non-verbal conversation between Pam and Jim was amazing! Great job all around.

Reasons I love this story:
1- ordinary detail juxtaposed with unique imagery (thinking of laundry, then...if he had made himself dredge up the moment when he bled the contents of his heart all over that dull, grey, ground then perhaps tonight he wouldn’t have tried to cover it in the colors of their future), also, Pam in her pajamas and him running to the store kind of blends into their perfect love story, and makes me remember that love doesn't always have to be shiny and technicolor to be perfect.
2- Phrases like "even though they’re the sort of together that means he can stride around her kitchen like it’s his own." Phrases like that perfectly convey an idea and the attendant emotion and tie a reader into the story because they perfectly identify with it. Phrases like that are not easy to come up with, I feel confident in saying.
3-Making us see Jim through Pam's eyes and Jim's eyes at the same time, for that delicate balance of "I know I'm ordinary but they think I'm more than that, and isn't that a great feeling"
You did this through the phrase "“Yeah I was,” he cuts her off, looking up with a face full of disappointment, a carrot in one hand and a block of cheese in the other. He thinks he probably looks absurd but she seems to be melting at the very sight of him, visibly relaxing into her seating position atop the back of her sofa."

And finally, I love this story because that is the hands down best proposal I've ever seen, in print or in person. Nice job!
