Come fly with me

There is this couple in the locked unit I worked tonight which you can tell they're in love. Locked unit is for those people that their dementia is so severe that they are danger to themselves or others and they need close and constant supervision. Lots of these people even don't remember their own names, most would never remember any of the workers even if they work on their unit full time. Anyways, these couple are always together. They sit at a same table for meals, they walk in corridor hand in hand, they sit in TV room or hallway together and she usually puts her head on his shoulder. If one comes late to the dinning room, the other one gets worried. You can tell that they are the only matter on each others minds but they never talk. Just once in a while one would look at the other one and ask "are you ok?" but that's about it. The lady is much sicker. She doesn't even remember her own kids, never mind the workers. But she never forgets the man who she holds hands with.
I guess love is the strongest feeling of all. That's the last thing you lose. I look at them and see two really sick people who have absolutely nothing. But then again, I see them together, and I envy them.
