Dear Kendra, I´m inviting you go to the cinema to watch the film "Robocop" on February 21st, next friday.
Dear Kendra, how about to watch the film "Robocop" Next Friday? (informal here, and either she will ask in what day it falls, or will see it on the calendar.)
Friday, or for that matter, any day of the week begins with capitals.
Actually, I´m not going to watch the film alone and I know well that/and as you like science fiction and action films. So your "yes" it´s very important for me.
I hope your answer! Ok? See you next and God be with you!
