As told by a nurse:

It was a busy morning, approximately 08:30 am, when an elderly gentleman
in his 80's arrived to have stitches removed from his thumb. He stated
that he was in a hurry as he had an appointment at 9 am. I took his
vital signs and had him take a seat, knowing it would be over an hour
before someone would to able to see him. I saw him looking repeatedly at
his watch and decided, since I was not busy with another patient, I
would evaluate his wound.

On examination, it was well-healed, so I talked to one of the doctors,
got the needed supplies to remove his stitches and redressed his wound.
While taking care of his wound, we began to engage in conversation. I
asked him if he had any appointment that morning, as he seemed
to be in such a hurry.

The gentleman told me no; that he only needed to go to the nursing home
to eat breakfast with his wife. I then inquired about her health.  He
told me that she had been there for a while already and that she was a
victim of Alzheimer Disease.

As we talked and I finished dressing his wound, I asked if she would be
worried if he was a bit late. He replied that she no longer knew who he
was; that she had not recognized him for five years now. I was surprised,
and asked him. "And you still go every morning, even though she doesn't
know who you are?"

He smiled as he patted my hand and said: "She doesn't know me, but I
still know who she is."

I had to hold back my tears as he left. I had goose bumps on my arm, and
thought: "That is the kind of love I want in my life."

True love is neither physical, nor romantic. True love is an acceptance of all that is, has been, will be, and will not be.
