Sebastian sighs softly, takes a moment to adjust the sleeves of his uniform. No helping it, is there?
"Can you indeed? Thank you for the kind gesture... but allow me to clarify." How very unseemly a clarification this will be, for a butler.
"I am perfectly unhurt, yet as it appears the powers of this world are set on ensuring people here spend the week in idleness... I would say the answer is 'I am simply tired'."
It probably would help, at least temporarily, if he'd actually give in and sleep already, but no, Sebastian has to be a stubborn mule.
