I have two people in my contacts with the same first name (let's call them John). One person, John Appleseed, I talk to all the time. The other one, John Doe, I haven't spoken to in years.
When I tell Siri something like "Where is John?" or "Text John What's up?", I'm frequently asked "Which one? John Appleseed, or John Doe?"
Other than deleting the unfortunate person who shares the same first name as someone I talk to all the time, how can I teach Siri that "John" always refers to John Appleseed?
