We all have our definitions of love--what it is and what it means. I used to think that love meant loving someone regardless of how they loved or didn't love you back. Later I decided that, with the exception of the love for a child, that wasn't true. At least not for me--I'm not that pure.
Recently, my brother Michael and I sat in our mother's kitchen, and he told me what he thought love was. "Love is when you love someone after time passes," he said. "After you know them, you still love them. That's love."
I think he's right.
