Sam both stopped walking and didn't stop at the same time, or perhaps it was the rest of the universe that missed a step. Either way, he seemed to stumble mentally as his head turned to stare at Louise, his eyes widening. He tried to prevent the grin - well, smirk would be a better description - that was slowly spreading across his face, together with his cheeks that seemed to be colouring, but to no avail. "That sounds... interesting..." he managed, glancing briefly around to make sure nobody was listening to their conversation "very interesting, in fact...I may have to add that to my list..." Actually he felt a little uncomfortable talking about such things, particularly in a public place that wasn't Louise's shop, but there was no denying that he enjoyed the conversation at the same time.
He didn't feel so much like walking now, but as they were still surrounded by people thre wasn't much of an alternative for the moment. "I got to sit down last night...at bedtime" he admitted. More accurately, Sam had sat down in one of the armchairs inside the tent the family was sharing, drunk half a cup of tea and then almost fallen asleep within minutes. At least he'd slept well, despite the bagpipe-playing that had gone on in the arena until...well, he had no idea. It could have continued half the night for all he knew!
"The astronomy position is open, and history of magic...I can't remember which others" he admitted, a little shamefaced. There was a time when he would have known everything that went on at Hogwarts, but now... He'd made the right choice to return, he knew, even if it did mean that life was even more complicated. "Yes, I think so. It's not unusual for a professor who has children or a family to ask for a regular evening off so they can spend time together. I remember someone asked me the same question when I was deputy headmaster, and we managed it then" he thought for a moment and added "Theoretically I would still be able to live in Hogsmeade if I wanted to, but with...well, it'll be more convenient for me to be at the school now." He would still have the house in Hogsmeade though, and it would be perfectly private if Louise were to apparate there to visit.
"Oh - I didn't ask. There's a lot happening in these last couple of weeks - but usually the professors' schedules are sent out a few days before school begins, so I should know then, I guess" he said.
The mention of coffee - and the smell of it - was more welcome that he could have imagined. Breakfast seemed a terribly long time ago now. "Double? Hmm, you don't think they offer a triple?" he asked, looking serious for a moment before breaking into a grin "Actually a cappucino would be great. The place where we had breakfast did amazing bacon and eggs, but their coffee tasted like it had been made with tap water..."
