Two for one deal

"Where have you been all day?" Dani questioned her twin, closing the door behind her.

"What are you, my mother now? What's it to you?" Daniela rolled her eyes, removing her shirt.

Her lips twitched when a strand of her hair got stuck to her bra. With a groan, she finally loosened it and put on a white tank top, with some black leggings and sneakers.

Dani shook her head. "You stayed the whole day with her didn't you?"

"And?"

"Are you joking? We are supposed to stick together. Why are you making useless friendships with that snake?"

"First of all, snake? If she's a snake then you're worse. As you said, we should stick together, right? Maybe try practicing what you preach." Daniela shoved her shoulder against hers and left the room.

Dani gritted her teeth. 

What is this? Why are things going wrongly?
