...actually now he's saying the 21st? Sorry about that... ;; i can time travel a day if you'd prefer to do it the 20th, or I can wait until the move date, either is fine!
EDIT: Okay, his dialogue was kinda confusing, he IS moving on the 20th (so, today). @_@ He said yesterday he'd leave the day after tomorrow, but apparently he meant he'd be gone that day, sorry!
