When Theresa reads the note she finds, she says, "... Realaty ... Realators...." The second "a" doesn't exist in either of those words. Realty is pronounced real-tee, and Realtors® is pronounced real-tors. Further, the title Realtor® is federally registered trade mark owned by the National Association of Realtors® and can only be used to identify members of that association and must always include the symbol ®. The generic term is real estate agent.
