Erin reached out for a pencil at her schoolbag for the teacher told them to take some notes. They were in Potions and with the subject; it was kind of a norm to take down notes. Her seatmate nudged, "Erin, we use a quill to write."

"A quill? But I don't have..." OH. She actually had one. But she was used to using a pencil for it was the usual writing material in the real world and not the world like this. There were times that Erin would just blink twice, just to make sure she wasn't at all dreaming.
