Quote from Dorothy in Mary Has a Little Lamb
Dorothy: Listen, this is the most difficult thing for a father to accept. Mary: What, that I'm a grown woman? Dorothy: But you're not a grown woman. Just because the plumbing's in doesn't mean the house is ready to occupy. Mary: I think I know what you're getting at. Dorothy: Good, because I really didn't make that up myself. I heard it on This Old House.
