Night owl (person)

Okay kiddo, a night owl is a special kind of person who likes to stay up really late at night and sleep in late in the morning. They are the opposite of early birds, who like to wake up early and go to bed early.

Sometimes, people who are night owls have a hard time falling asleep when it's still light outside, and they feel more awake and alert at nighttime. They might like to read books, watch movies or play games when everyone else is sleeping. It can be fun to stay up late, but it's also important to get enough sleep, so night owls should try to make sure they get some restful sleep too.
