Carrie Post is a pre-made mailwoman from Twinbrook. She can be made playable by marrying her or asking her to move in. She is 17 days from becoming an elder. Her name is a pun on the term, "carry post". She shares her first name with the mailwoman from the original The Sims base game, and her appearance is very similar to that of the original Carrie; it is possible they are intended to be the same character, or that this is at least an intentional reference. Since The Sims 3 is 25 years before The Sims she could be an ancestor of the original Carrie.
