#Idiom a night owl Meaning: Youre a night owl if you like to stay up and do things late at night. For example: Shes always been a night owl. Even when she was a student shed study late at night and get up as late as possible the next day. I dont know why Im a night owl. I just seem more alert at night, and even if I go to bed early I cant get to sleep till about 3 in the morning. @EnglishExcellence @Curiosity_Tea 872 views18:50
