After working a whole day, when Lois, a nurse for thirty years, left the hospital, she was asked to take part in a rescue of a car accident.
They soon arrived at the accident site. While doctors attended to an injured man in one car, Lois checked a woman sitting in the other vehicle. There was no blood or visible sighs lf injury and the woman said nothing, but stared at Lois with vacant eyes.
On the way to the hospital, Lois held the patient’s hands and comforted her by telling her that everything was going to be fine.
The following morning Lois entered the room and introduced herself. “I’m Lois, your nurse. How are you feeling?”
The patient blinked her eyes and her face turned white. “Are you real or am I hallucinating?”
“Oh, I’m real, I assure you.” Lois gently held the woman’s hand and checked her pulse.
“A…are you sure you are not a …an angle?”
Lois smiled, “Nurses are often referred to as angels of mercy.”
Her patient continued to stare at Lois and whispered, “I mean a real angel.”
Lois raised her eyebrows. “A pair of wings would be handy, but, believe me, I’m just as human as you are,”
The woman shook her head. “Last night I was in an auto accident and thought I might die. Suddenly an angel appeared. When she touched me, I knew God sent her to
reassure me that I’d live.” She held Lois’ hands tightly. “You look and sound exactly like her except that you don’t have wings!”
