Your Anniversary Is Wed-Locked

(I am having a conversation with my 92-year-old mother for my parents’ anniversary:)

Me: “Happy anniversary. Sorry I couldn’t reach you yesterday.”

Mom: “I don’t know where we were, but can you believe we’ve been married 73 years?”

Me: “74 years.”

Mom: “No, 73 years.”

Me: “[Sister] will be 73 in three weeks. Did you have her three weeks after you got married?”

Mom: “No! We didn’t do it like that back then. Guess I’ve been married 74 years.”
