Snape was already way ahead of Barty, realising that the more he prolonged this, the more he had to actually talk to Barty. So, with great reluctance, he sighed like he was pained, closed the paper and rolled it up. Holding it out, he let Barty take the paper from him and leaned back in the seat he was in, debating when was best to get up. He didn't want it to seem like he'd been chased out of the room.

But he also just didn't want to be in the room. Merlin, why did people have to exist? "Enjoy." Cause he certainly wasn't enjoying anything about this. One of them may as well get something out of it.
