"The telly?" he said. "I can't believe you two have one of those things. I forget you're Muggle born. The first time I saw one of those when we moved out to Wales, I was shocked. I thought it was the finest bit of magic I'd ever seen, and then I found out it was a Muggle invention! Amazing. Maybe Sirius and I should get one for the flat."
He shrugged a little.
"Maybe," he said, regarding the date. "Maybe you and James could come? A double date?"
A double date would certainly be less pressure on him. He wasn't great with idle chat. Having friends there would ease the tension a little.
