[Carter's Financials] Kayla Works as an Accountant

[Carter's financials] Kayla works as an accountant. Rudy, an attorney, is working on a case for Carter, who is suing his business partner.

Kayla meets with Carter, who provides a lengthy explanation of the financial statements and facts of the case. Afterwards, she prepares a memorandum for Rudy outlining her analysis of the financial issues of the case. Kayla runs into Carter at a baseball game several months later. Carter tells her that the stress is getting to him and he wants to move to Florida because he can no longer tolerate his business partner.
