They take a cab home

"You know Lizzy, it's not even safe to ride with her when she's sober", Roxy warily reminds her friend. "Let's call a cab and leave our car here." An exhausted Candy agrees.

"Sorry, sis", she says apologetically. "But drunk friends don't ride with drunker friends, and that is even more true for close relatives. We're calling a cab, do you want to come with us?"

"Nah, you sissies, I'm fine to drive!" Lizzy snorts with open contempt. To prove her point, she grabs another beer can from the six pack on the passenger seat and throws the empty at Candy's head, narrowly missing her sister's temple. "Do what you want, I'm out of here!" She guns the engine and speeds off while Roxy rummages through her purse for her cell phone.
