NURSE JOY MUST BE A SADIST FOR ALWAYS SAYING 'WE HOPE TO SEE YOU AGAIN' LOL; WHAT? NO WHY WOULD IT BE? IT'S PROBABLY JUST A 'DON'T DIE OUT THERE' KINDA STATEMENT; WE KNOW FROM LEGENDS ARCEUS THAT LEAVING THE VILLAGE USED TO BE DANGEROUS. SO IT'S PROBABLY SOMETHING THEY SAID TO PEOPLE WHO WERE LEAVING... BUT- BUT FUNNY SADIST NURSE JOY... AND IT STAYED AS A TRADITIONAL FAREWELL IN POKECENTERS
