Merlin, Hermione hated feeling ignorant. But all of the technological electronic stuff that this woman was spouting off, it was all going entirely over her head. She didn't spend much time at home with her parents, so while she was familiar with the Internet and its capabilities she didn't know if she could provide any help or suggestion. Hermione itched to touch it, to have a go herself, but without a connection to the outside world or any source of information -- besides whatever the devices were connected to -- it'd be useless to her.
"You didn't buy that here, I'm assuming?" If they sold those computers in Marrowood, Hermione knew immediately what she would be saving her coin for. But she'd only arrived with a few things; she didn't think more was possible. But then again, who really know what all was possible in Marrowood?
Something about the way she spoke, though, was familiar, even though they were strangers to each other. "Are you Velma? I think we spoke on the devices; my name's Hermione."
