Done helping ..

My niece is 15yr old. I often stop what I’m doing to pick her up from school or to even drop her off. The last few months she been having a ride but her aunt said she not dealing with the bad attitude she has. She came up to me asking to start picking her up from school. She tries to fight about who sits in the front or back, she gets in don’t even say hi. She also goes around the family talking to everybody like we’re beneath her. I understand she’s a teenager but it gets super annoying, especially when I’m going out of my way. I’m guessing yesterday she was mad because I didn’t take her to store late at night but who cares 🙄.
