I think it’s probably normal when you lose someone to wonder “what if?”, and second guess yourself and your actions. Could I have done things differently, done things better, made more of a difference? And, because we’re human, and don’t always treat other people—even the most important people in our lives—the very best that we could, the truth for most of us is that we probably could have done better.
But in some cases, and certainly with my grandma, I’m confident in the idea that she thought I did enough, even when I am not so sure. And, the thought that brings me more comfort than any is that the last thing I said to her, just hours before she passed, was, “I love you.” I am convinced they are the most important words in the world, and can never be said too often.
