They hadn't watched it the first time around. Dwight had been interested in seeing their relationship from an audience's point of view and was curious to see how much the documentary crew had really found out, but Angela disagreed for the same reasons. She was afraid to see what was caught on camera and discover what secrets were revealed to people she'd never know.
People had approached her on the street a few times. The responses she received depended on the timing, how far into the series the person was. Within the first few weeks, people told her how adorable she and Dwight were together. By the time Andy had proposed, a few people were calling her rude names (though her husband always put a stop to it if he was around).
One woman asked how she could possibly sleep with a man like Andy. Angela tried to insist that she hadn't ever gotten that far with him – for years she'd been fairly successful in blocking out the memories – but people would debate with her. "Andy said you'd slept with him twice. He was in the car, when he was dueling Dwight! He told him!" She couldn't argue.
The responses were creeper by the time the contract was being shown, and she would never respond to any comments regarding it (although if you look closely, you might catch a subtle smile).
One time someone jokingly shouted "Monkey!" to her on the street, and, although she was uncomfortable, Angela laughed it off. She'd been called worse things.
Halfway through the series, Angela asked Pam how she was dealing with the attention. She and Jim had just gotten married on television, and she'd been congratulated numerous times by fans on the street. But Pam couldn't give any relevant advice. Most of the feedback she'd received was positive, but Angela's audience seemed mostly negative.
While some of the comments weren't rude exactly, they still didn't seem praiseful. It was clear in most cases that, even if the fan of the show wasn't against her, she wasn't the favorite. They'd much rather run into Michael Scott on the street.
She wouldn't say that the show ruined her life, of course. Angela had everything she wanted, the man of her dreams, three beautiful children, two dozen cats. And Mose. But the documentary placed an extra burden on her shoulders and made it nearly impossible to leave her house for several months.
So it wasn't until two years after the initial release, once the buzz had finally died down, that Angela decided to watch her life on film.
