Myself - I would call Myself an Early Riser because I go sleep early and wake up at around 6am to 8am most of the time and I get up make breakfast and clean my Bed.
Older Sister - I would call her a Night Owl because she always stays up on her phone or Chromebook. She usually wakes up at around 12pm to 2pm
Younger Sister - I would call her an Early Riser Like me. She wakes up before me sometimes at like 5-6 and wakes me up because she is hungry for Breakfast.
Mum - I would call her A Night Owl because she stays up watching movies on Netflix while we are sleeping. She wakes up at around 11am to 12pm.
