When a man pretending to be her father tried to force his way inside, a six-year-old girl noticed one small detail that saved them: her real dad always knocked four times. Trusting her instinct, the mother hid and silently alerted her husband, who called the police.
The intruder fled just before sirens arrived. Later, authorities confirmed he had been impersonating traveling spouses. The family was safe—because a child listened closely and knew when something didn’t belong.
