I  just can't go to sleep early!  I love to stay up until really late at night, which makes me a night owl!
I am more of an early bird. I go to bed rather early and wake up early too.
I hate mornings!  LOL  Interestingly, in Scandinavia early birds and night owls are called A-people and B-people!
I guess it has to do with the type of personality someone has.
I guess, or their circadian timing system!
Maybe so!
It's funny that an early bird is sometimes referred to as a lark!  So you have night owls, and larks!
That makes sense. I think of an early rising bird when I hear the word lark.
I only just learned that night owls feel the most energetic right before they go to bed!
