Juan Jaramillo told WPXI that someone stole lights from his home on in Monroeville, Pennsylvania.

His family was so upset that they posted a sign letting the person responsible know how they feel.

The sign reads: “To the person who stole our Christmas lights thank you for breaking two little girls’ hearts. I hope you are proud of what you’ve done!!!”

Monroeville police said they’re investigating a report of Christmas decorations stolen from outside the home between 8:30 p.m. Tuesday and 8 a.m. Wednesday.

The family says the lights on their fence were taken and the lights on their house were not.
