Every day, a young girl would stand at her window and wave at the passing police officer. It had become a routine for both of them, a small gesture of friendliness in an otherwise busy world. However, one day the girl didn’t wave at the officer. Concerned, he decided to check on her and make sure everything was okay. When he arrived at her house, he was shocked to see the front door wide open and signs of a break-in. Thanks to the girl’s absence-minded wave, the officer was able to prevent a potential crime and ensure the safety of the girl and her family.
