Two sisters in Edmond, Oklahoma were having trouble sleeping, fraught with worry over whether their home was safe from crime. Their mother even began showing them the locked windows and doors each night and allowed them to sleep with baseball bat under the covers.

Then, Lt. Paul Barbour, on his night shift patrol for the local police department, took a few minutes to pen a hand-written note to the girls assuring them that "everything looked good" in their neighborhood. He taped the note to the door, having learned about the trouble from his wife, who was a friend of their mother.

The note did the trick, and the sisters, ages 9 and 11, are now sleeping with the lights off again.

"I felt a lot more safe and secure knowing that someone is watching after us."
