‘What is love?’ Sweet short film finds the answer

What is love?

Film company cvcnow attempts to explore the question with a short film sure to warm even the greatest cynic's heart.

The answer certainly goes well beyond chocolate hearts, red roses and cardboard valentines.

"Do marriage vows seem to mean as much today as they used to? If you’ve heard anything about the increase in divorce rates, you may wonder," cvcnow posted. "Bill & Glad are ignoring the trends. More than ever the vows they made 50 years ago are being tested. In sickness and in health, in good times and in bad, the promise they are keeping is a true example of what love is."

Watch Bill and Glad's inspiring story below. (First, grab a tissue — and a loved one.)

"I count it a great privilege to care for this woman I've loved all of these years and continue to love," Bill narrated.

"I am determined to care for her every need," he said, later adding, "She's my princess and I'm her William….I wouldn't have it any other way."

Cue the empty Kleenex box.

"Literally sobbing. This is beautiful," one viewer wrote on YouTube.

Others, inspired by Bill and Glad's love story, shared their own stories of long-lasting love:

"I don't think this type of love is just found. I believe you have to work for this love every day and never give up on it. After fifty years of loving someone true and faithfully this amount of commitment will just make sense and doing anything different just wouldn't make sense. I applaud this couple, my idols are my grandparents both in their 90's going strong over 70+ years of marriage," wrote viewer moksaam.
