I'm so sorry to hear of your loss. It is good that you give your mother support in her time of mourning, for as you say, she has lost a piece of herself. You are very lucky to have had a father who instilled in you his life knowledge, and his valuable thoughts and ideals on living a good life.
Thank you so much. He was the best person on earth and he taught me well.
Of this, I am sure. :)
