Im pretty an evening person or simply owl, is a person who tends to stay up until late at night.Guess you can call me a Night Owl ...Lol!
I am a night owl as well.  What time do you usually stay up til?
opposite of a night owl is an early bird, a lark as opposed to owl, someone who tends to begin sleeping 
My wife is more of an early bird.  What causes people to be one or another?
We also have the bird dinner is a dinner served earlier than traditional dinner hours, particularly at a restaurant.
Do you mean an early bird dinner?  What time does that usually occur?
Do you find it difficult doing stuff early a times?
Yes I do.  It takes me a while to wake up and function.  I usually need a cup of coffee!  How about you?
Same too, though i actually love dinner night party
I enjoy a good nighttime dinner as well.
