That was a great article, thanks for sharing.
Working in healthcare I have seen LGBT clients hide their sexual orientation for a long time and then tell me or someone after a few months of working with them. If they were living with their partner they would refer to them as their friend or roommate. On the other hand though I've seen clients that were very open and their husband or wife would visit daily.
The other thing with assisted living facilities although there are some that will say they are LGBT friendly the other residents may not be so friendly...elder bullying is pretty common unfortunately.
