Boyfriend meeting parents tips

Hey everyone, my bf is meeting my parents for the first time tomorrow as he is taking me to dinner for my birthday and he will be coming to my house before we go out, I will be 20 tomorrow and my bf is already 20, I’m just nervous because my parents will embarrass me as I’m not very open about this kind of thing with them and it’s the first guy I have brought to meet them. What can i talk about with them all and make it less awkward?
