Please when commenting, remember that there are ALWAYS two sides to everything. It is just possible that the elderly lady could be seriously ill and, for whatever reason, is unable to call for help herself. Just maybe, she is calling for help and that she is hoping a neighbour will call the appropriate authorities.Maybe that her partner is also seriously ill or they have no other way of contact. Very unlikely ,but it could be possible. Kim's comments were exactly correct and a friendly chat with person involved could solve the problem..
The original message re "overweight" etc are irrelevant. But it just could be that help is required. Please remember always, that there are always 2 sides to everything, whether you like it or not !
