Night owl's and Early risers

I am a night owl, my family there is only one person who is a night owl my sister Hannah the rest are early risers especially my mum. My mother goes to bed at a responsible 9:00 / 9:30 and wakes up at 5:30 to get ready for a new day. So basically me and my sisters are the night owl's and my mother, father and two of my other sisters are early risers.
