You think Millennials are bad? Get a load of what's coming after them.

This teenage girl in a mall throws a classic teenage girl hissy fit and drops a minefield of F-bombs at her grandfather because she thinks they're going to miss their appointment to get her iPhone fixed. And we assume the phone needs to be repaired so she can text her friends about what a loser her grandfather is because she sounds like the type of person who would do that. She doesn't come across like a girl who volunteers at a nursing home.

Wow. Just wow.

We're not sure which streak is bigger -- the green one in her hair or the mean one in her soul.

Who would speak to a grandparent like this? This is the man who bounced this ungrateful girl on his knee while she laughed and had snot running down her nose as she playfully called him "Gampy" and looked at him like he was the most important person in the world. Now, she has daggers in her heart as she yells at him like an Uber driver.
