I guess she's talking about stillbirths and miscarriages. But are the people in these sad situations, which must be a minority of patients, going to feel better because of the gray walls? The nurse's comment is just weird. Wonder if she's got some baby-related tragedy in her own background, in which case she should, respectfully, consider a move to another area of nursing rather than rain on others' parade.
Nurse Ratchett is not referring to stillbirths, miscarriages, or adoption. She's referring to pre-natal homicide. Most hospitals are involved in that despicable industry.
