What does my mother mean to me?

My mother means more than I would ever have words for. She had passed away four years ago and since then I have always looked back on each thing she's ever said. If she were here I would want to ask her things I never thought of while she is alive, but she is not. I would want her to teach me how to cook the crap she made, but she can not. You never realize how much you appreciate and rely on her until she's gone.
