I Hope You Don't Forget

In "Enchanted," Robert tells Giselle that he worries about his daughter, Morgan, that she doesn't have many friends. He tells her that he wants her to be strong and not believe in the "dreams come true" nonsense. Giselle tells him that dreams can come true and that maybe something wonderful will happen. He replies that he forgot who he was talking to, leading her to tell him that she hopes he doesn't forget, that she likes talking to him.
