— ... And you once had a Japanese girlfriend that meant a lot to you, but now you feel indifferent about. <...> You've got a Japanese tattoo in the crook of your elbow in the name Akako. It's obvious you've tried to have it removed.
— But surely that means I want to forget her, not them I'm indifferent.
— If she'd really hurt your feelings, you wold have had the word obliterated. But the first attempt wasn't successful and you haven't tried again. So it seems you can live with this slightly blurred memory of Akako. Hency, the indifference.
