If you ever wonder whether you can make a difference in someone's life, look at this 1988 picture from Children's Nurse magazine.

The nurse on the left is Lynn Bartos, who spent years helping treat the little girl, Nichole Frye, who had been born with a serious birth defect.

The girl called the nurse "Sweet Lynnie" and the nurse called little Nichole, "Ninni."

After almost 25 years, the two met again by chance, and Lynn learned just how much she did make a difference in her patients' lives, when the roles were reversed.

This time, she was the patient-in a hospital being treated for rheumatoid arthritis, when a young nurse came in to adjust her medicine.

Lynn felt something familiar about her and read the name on her name tag.

"Ninni?" she asked.

Sure enough, little Nichole, now 30, had followed in the footsteps of "Sweet Lynnie," the nurse who inspired her as a little girl and nursed her through years of surgery and treatment.

"When you get to be my age, you look back and wonder if you made a difference," she told the Milwaukee Journal Sentinel. She found out she really did.
