"I'm not in the mood right now."
"Bad day at the office?" - the tone of voice reminded him of the way it used to be, back when he was in school. Snarky. Haughty.
"I'm really not in the mood." - he gritted again, bringing his hand to his head. Ahh... that got his attention.
"Are you okay?" - the tone of voice was softer now, more aligned with how things are now: older, more tired, less ego.
"Just... a headache... You know... caffeine."
"Oh."
He disappeared with a swirl of black robes into the bedroom. But then he returned, and the lights were lowered, less harsh. And he was moving quietly.
"Try this." - an offer. A bottle in his hand.
And Neville was reminded once again of the many joys of being involved with a Potions Master.
