Because of that they weren't exactly the best of friends. They fought all the time,but there mom told them to go do something. So they went for a walk,during the walk they ignored each other till they got home.
"Oh bye and by the way don't go in my room again" Emily said as walking into her room.
"I wasn't in your room whatshername" Mandy said following her. Emily had a strict rule that no one called her by her real name.

"Yes you were and don't you lie to me" Emily said back.

"Okay that's it you too are going to play together you know what sense it is already 10:00 at night and I am going to bed and also you guys can play mine craft" Christina said. Christina was there mom if you didn't know that.
Their mom walked up to the room when Mandy had already had turned on the game console and logged both of them in. Emily put on her music then grabbed a controller.
