"I haven't had much contact with the Muggle world in almost ten years, stiles. It's distinctly possible something I knew isn't there anymore. My sister had a flip phone, I understand those don't exist anymore."

That made him pause, despite Stiles' instruction, and look up at him. He bit his lip because...that was probably not appropriate, a teacher at a student's house. But Stiles and Isaac were in the same house and there's nothing to say that they weren't friends, or something like it, and he was right - Isaac could use some time outside of school, beyond just short trips to Hogsmeade. "if...if your father says it's okay. We won't intrude where we aren't welcome."
