Why is David being invited?

W: I really can’ t stand the way David controls the conversation all the time. If he’ s going to be at the Christmas party, I just won’ t come.
M: I’ m sorry you feel that way, but my mother insists that he come.

W: We do need another bookshelf in this room, but the problem is the space for it.
M: How about moving the old dining table to the kitchen?
