"Of course Sir," he answered at once, wiping his eyes and getting his emotions under control, mortified at the slip in front of all people. He wasn't the crying type but things had been a shock these last twenty four hours, and he looked at Severus, frowning slightly at first as if he didn't hear him correctly.
"A job? You're offering me a job. Honestly?" and without pausing for confirmation, he rushed on, "I'll take it. Of course. Definitely. I can do it. I'd be happy to do it," and then he paused hesitantly adding, "It's just for the grounds keeper position right? Because I'm okay with animals but not all that brilliant at them," and he hesitated again, "I mean, if you needed to me, I suppose I could try," and he nodded emphatically as the words sunk in, "Interview? But..but when? I mean, do you want me to start right away? Because I can you know," and he was sitting up, leaning forward now, his eyes bright.
"I'm your man, Sir. I can do the job, I'm certain," Greg announced with clear certainty.
