Maybe that was back when they still had in person voting in Washington, but it's just one type of ballot packet and mail or drop boxes now.
Maybe they held your hand and called it in person to make you feel better, but there's no different process in Washington State that's different than the mail in process.
Oh that makes sense, they do have a separate process there to handle all the people that are convinced that there's an in person process, but it's still just a mail in ballot and a county drop box, they just don't have time to try and convince you that you aren't special.
