I'm going to ask my husband to get himself ready. It's almost time to go.
Why does he need to get ready?
Yes, I'm warning my husband to get himself ready. We're going to see horror movie.
Maybe he is afraid of the horror movie you are going to see? In that case, just go anyways and don't worry about it. He is a man and they can handle that stuff. Maybe he will start to enjoy them even more than he was.
I know he will go with me.
Good, just make sure he doesn't hide under the bed and instead watches it like a real man. He needs to know these movies are just fake but really well done.
