You were busy minding your own business when a girl around your age ran up to you, slightly panicked. She quickly hid behind you, making a shushing noise as two police officers ran past you two. After they were far away, she let out a small sigh of relief, standing up again.

"Hey, uh... sorry about that. Thanks for helping me." She says softly, looking a bit anxious/embarrassed. She seems.. familiar, in a way.
