I think cassiopeia my query is related to the "reason". discussion could be..
Man: Are you going to be Mrs Man
Woman: No, I will keep Woman
End of discussion
But discussions dont happen like that between partners. I dont think I could ever have a discussion like that with someone Im marrying - someone I work with yes, not someone Im marrying. This is more the type of discussion we'd have:
Man: Are you going to be Mrs Man
Woman: No, I will keep Ms. Woman, do you mind? (aside: I love him I want to know if he minds)
Man: No not really, I think mum's going to be upset
Woman: Yeah, but, Im not marrying your mother
Man: Speaking of mothers I dont have to sit beside yours at the wedding do I?
Woman: No, I think youve got the priest on your other side.
Man: You're kidding? Your mother isnt free? Can I tell the priest I think God is as real as santa claus?
...and so on...that was the jist of our discussion.
