Believe it or not, this is very much like the real Luna.  She takes things very literally and seriously.  It makes joking around with her difficult sometimes.
She corrects us a lot too.  In really unimportant ways.  Like if I say, “Turn of your TV show, it’s time for dinner.” Luna will correct me that it’s not a TV show, it’s a YouTube channel.
WHATEVER! Just shut it off and eat your dinner!
