Exhausted Houston Police Officer breaks down in tears as daughter sings him Happy Birthday over the phone

An exhausted Houston Police Officer catches a break -and sheds a few tears- as his four-year old daughter sings “Happy Birthday” to him.

Sergeant Nick Matson had not been home in six days due to the storm when he managed to get a hold of his daughter, who sang the birthday song through the phone.

Matson wiped away tears and cheered on his daughter as she finished the song.

According to the Daily Mail, the officer has a third child on the way.
