Continuity mistake: In one episode Angela says she hasn't talked to her sister in years over an argument that she doesn't remember. When she's engaged to Andy and they're touring Dwight's farm he mentions she has multiple sisters. In the finale she only has one sister and apparently they are incredibly close.

Suggested correction: In the finale the "Sister" is Angela's best friend. Do you recall them each saying this is my older sister?
That's a common joke among siblings that are close, they're joking about which one is older. Rachel is Angela's sister, not just a friend. They even go on to say "we're very close. We even have our own special language", which is something common among siblings that are close. The mistake is valid.
