When I say Night owl it refers to a person that likes to stay up late in the evening and early bird is someone that likes to wakes up early.
I like both because I like to stay up late and wake up early. Sometimes I don't because I get put to bed early on a school night☹️😞 but I ready to wake up for school.😀
If I was only allowed to pick one I would pick a.... early bird because I am the one that wakes up first unless some family members are starting work early,going to the gym or walks.
I sometimes get bored if there is lots of people staying at our place because that are all sleeping an it will be rude to wake them up!
If I would pick one for my family I will say it is Night Owl because they are always sleeping in the morning once my brother woke up at lunch time!!!!!
