Ask them to take you to the library

The girls look surprised, then exchange some complicated and - to you - impenetrable information through a language composed of eyebrow raising, pouts and shrugs. Then the girls aggressive link arms with you and begin to march you down the streets.

"Hey, look, you're taking me to the library, right?"

The tall girl hijkes her eyebrows almost up into her hairline, looks down at you and says -

"Sure...if you wanna be like.... boring and all."

Then she looks away and pretends to be chewing gum, and the two girls continue to frog march you along the street.
