Firefighters are known to be rough and tough and not known for being emotional, but this clip will make you think otherwise.

In a video posted to Instagram, firefighter father Justin Gigliello sings “Ave Maria” while his daughter, Layla, looks on.

He approached him and asked the pianist if his father and the pianist could have a duet, while his father sang, he could play for him.

The pianist happily obliged, and when Layla’s father began to sing, you could see how happy he was.

This firefighter dad’s gesture for his daughter surely won her and many others’ hearts. It just proves that there is no greater love than that of a father and a daughter.
