It means perhaps it will put you and your all too youthful 'attitude' into perspective. Or one can only hope. I couldn't care to begin with.
I don't have time to listen to whining or complaints. I have little interest in what you do or think. I have work to do, as do the rest of the shinigami who want to stop this pest before she does something irreversible.
I can't be bothered with what a mere substitute does.
