Typing on the phone might be faster, but Regan's already committed to using her notebook, so after she reads the girl's message, she lowers her pencil to the page again.

If you know how to sign (in ASL) then that would be better, but if you don't, then this is fine. Most Hearing people don't unless they have a reason to. She looks up at the girl before turning the page to face her, and adds, I'm Regan. I like your hair.
