From the moment he walks her down the aisle to the tears that may fall during the father-daughter dance, dear old dad is a very important part of a woman's wedding day.
It's never easy for a dad or a woman's father figure to give away his "little girl" to the man she loves, but it's such an extraordinary gesture that means the world to both of you. One dad wasn't sure how to tell his daughter how much she meant to him on her special day, so he decided to do something extra special to let her know he will always love her.
Nicole Cortez posted the following video on YouTube of her father signing the song "I Loved Her First" by the band Heartland. Although Cortez is not deaf, she is a sign language interpreter and was surprised and delighted that her dad learned to sign for this amazing tribute.
Cortez said on YouTube: "This meant the world to me. He said it took him the entire year I was engaged to learn how to sign this song." He did a great job and you could see how it even moved him to tears to perform it for his daughter.
Watch until the end so you don't miss the very best part: Dad signing "I'm watching you" to his new son-in-law!
