I've seen a few. They were okay. They were nice about visitation and celebrated quite often. Their care was adequate to good. Web rider pretty much said it.
The environment is usually quite a caring one wherever and whenever I have visited one.
Still there is the undeniable air about the elderly of regret for their age. Other than consolation we can try to offer--I really don't know any way to soothe that. Visting, pets, gifts. Those help.
Some are happy and un-regretful. Those ones are the real inspiration I think.
