"Does it make you sad to talk about your dad?" I'd say: "No, it makes my happy. He was just so wonderful". Now, she will understand.
You can not believe how much that helped me. My father died last year and my brother died in January. My mother is in failing health and I am not dealing with any of it very well. I will keep your words in mind. Prayers sent to you and your family.
I am so sorry for both of your losses. I wish that there was something I could say to ease your pain.
