I'm definitely not a night owl. I like to get to be somewhat early.
I'm a night owl. I woke up at 2 p.m. yesterday and it's 6:38 a.m. now. I love to stay up late at night.
My brother is like that. He and I are wired very differently. He cannot get up early in the morning either.
Do you also go to bed early? If so, you could call yourself an early bird.
