I say, "I love you" to my friends and family; to people that I truly like or have impacted my life in some positive way. I believe that love is religion. The more you spread it, the more you'll find it; and it can be anywhere.
So, I say it when I leave and sometimes on the phone. A lot of my friends do too.
This past week, I was very grateful that I have said, "I love you," as often as I do, to a particular friend, Ali, who just got into a very bad motorcycle accident. He's one of his group (of real cousins) that I call my "cousins". Ali is a happy, sunny guy who is never down.
