Continuity: Right after Season Two's 1st episode, The Dundies.
Pam stumbled out of Angela's car, mumbled an apology and a Thank you and somehow managed to get inside the house without making too much noise or tripping over her own feet. Once she got to her bedroom, she quickly took off her clothes, changed into her pajamas and collapsed onto the bed.
She fell asleep.
Hours later, the shrill sound of the alarm clock woke her up. The second she opened her eyes she started feeling terribly sic and dizzy – that was when she remembered the Dundies, the party, and drinking a lot more than she should have, and she understood.
Something was missing, though.
There was some sort of blank in her memory, and she knew she was forgetting something, something important, but she couldn't put a finger on it. She shook her head in frustration, knowing that it's going to bother her all day long – that, if at any time during the day she could get past the fact that she felt awful.
So this is how the morning after feels like, she thought as she slowly got ready for work. She had never gotten so drunk before, and she made a mental note of never doing it again. It wasn't exactly the most pleasing experience of all times.
Suddenly, a blurry, slightly vague image popped up in her head.
"…Um, so, finally, I want to thank God. Because God gave me this Dundie. And, I feel God in this Chili's tonight."The woman held her award up for everyone to see it, shouted in excitement, smiled from ear to ear, hugged her boss and gave him a kiss on the cheek. Then she ran towards a tall, handsome, grinning man who applauded enthusiastically, standing next to the closest table and proceeded to hug him as well before giving him a quick, almost fleeting peck on the lips. As she turned around and slipped back into her chair, the man, looking happily confused, did the same, not knowing exactly what had just happened or how to react to it. He didn't even dare to look at her directly. And since he wasn't looking, he didn't notice her sighing deeply at the same time that he did, both too lost in their own contemplations to pay any attention to the person sitting right in front of them.
Not even when that person was the center their thoughts revolved around.
She blushed deeply. How could she dare to even imagine kissing her best friend? She had no idea where had that mental picture come from, but she decided to forget about it, and she passed it off as a drunken delusion.
Yeah, it was probably a dream.
