Ouch.. i'm really sorry
Not okay for any of you.. including the elderly ladies that are being really difficult for you.
If they're being disturbed every time anyone goes outside for a smoke at nighttime, can they possibly be moved so they're in a part of the building where they won't be disturbed?
Staff would obviously have to be careful, since moving someone with dementia to a different location can be difficult for them.. but perhaps that could be a helpful solution if staff plan and do it properly xx
