night shift was tiring. You came out and got into your car. Rubbed your eyes a little and started the engine. Driving through the sleepy and peaceful city and heading back home. Your music playing, bass heavy too keep you awake, and fingers drumming on the wheel.

She goes to school and does whatever young sisters do while you go work and take care of your little family. As soon as you entered the driveway to the house you spotted another car there. You parked the car next to it and got out, walked to the front door, opened the door with your keys and got in.
you can hear muffled laughing and talking from upstairs. Oh. You forgot. Mika told you that she’s inviting friends and having a sleepover tonight. “Please, I’ll behave and do the dishes for you” or so she said. So you said yes. What could go wrong?
