In college I worked in a nursing home. Once I was in a woman's room (she was fading fast) and she said, "There is an angel standing behind you." I asked, "Is he here for you or me?" (I was 21.)
She said, "For me," to which I answered, "Then I'll leave you two alone."
When I went into the room half an hour later she was gone -- and had a smile on her face.
Another time I was doing home health-care at a guy's house. He was 90 years old, and had outlived his wife.
He was lying on his bed one day, muttering, "I'll see you soon....I love you."
I thought, oops, and half an hour later he was gone.
It was an interesting job.
