I'm sitting here with tears trickling down my face. Thank you for sharing this, it's wonderful.
What you said to Hobbs is exactly what I said to my dad the day his mortal remians were reduced to ashes. I know that his soul, his essence, the thing that made him irreplaceably HIM had long departed, but it still hurt to have to acknowledge that he really was gone.
It hurt then, it hurts now, and I have a feeling that it will probably hurt for quite some time to come - perhaps even forever.
Tell Sabrina that I'm here for her if she needs me, and know that I'm here for you too...even if I'm just a shoulder to cry on and an ear to bend.
Make the most of your time with him whilst you can, and make sure that he knows you both love him.
I wish there was more I could do.
