Fan Casting Phoneaholic Teenager in Sort by Tropes

A teenager who treats her landline phone or cell phone as if it were the most important thing in the world and is on it constantly. This almost always leads to an insanely high bill. If she uses a cellphone, she may feel more comfortable texting than actually interacting with other people. When she has to babysit kids, she might not care about them. Her preferred place if the phone is wireless or a cell phone is her bedroom, and she will be invariably shown lying prone on her bed, languidly kicking her legs back and forth and/or wriggling her feet while gossiping with some female friend, or maybe her boyfriend.
