So so sorry to hear this, Mark. It's a terrible thing to lose our best friend.... and the mourning is painful. It truly feels like a piece of you, your heart, went with him.... nothing I can say can make it feel better. You were good for him, you gave him all your love and he gave it back. He knew what is is to be loved and that is so important. It doesn't make you feel any better, I know.... sending you hugs, my friend...
