She'd probably be scared by the fact that a complete stranger is reading her screen.
Pretend to look like you aren't paying attention to her
Bump into her gently
Say "Sorry," glancing down at her screen
Raise eyebrows
She replies "It's okay" and then asks what your looking at
"Oh you're a fellow blocklander?"
They talk, get to know each other
Ride off into the sunset
