why do you say that divebuddy? Is she being abused? Is there evidence in the post that she has severe dementia? I agree her lifestyle is not one that i would choose but that alone doesn't make her vulnerable. Until I retired, i worked in the NHS in the community supplying a rehab service to older people. Believe me, I know the story on what does and does not count as vulnerable or not competent....even then, so far as is possible, the lifestyle choice is left to the person. It stops being their choice at the point where there is a public health or safety risk, not a risk to the person or their visitors but to eg neighbours; or the person becomes so severely demented that they are adjudged not to be competent. Even then, if the person has a chosen lifestyle then every effort is made to support the person in that lifestyle.
