I am not sure what has changed in my dad's life to prompt him to verbalize his affection. For some people, it could be an illness or a challenging time that causes them to reflect on their relationships and change their behavior. For others, perhaps therapy. To me, it doesn't matter why he has emotionally opened up. I am just happy to be the beneficiary of this sentiment.
Today, please tell those special someones in your life that you love them. Hugs are wonderful, but nothing beats a genuine, verbal "I love you." You will not only brighten someone else's day, but I guarantee that your divine light will shine all the brighter because of it. Spread the love!
