Sam, sorry to hear of your loss. My sincere condolences to you and yours.
I remember 2008 when my mom passed away very well (my father went way back when I was 15... too too many years). Of course I was sad, but I carried my camera to the wake and funeral, and to the burial, and to the reception afterwards. My brothers and their families were somewhat taken aback then, but I kept making photos anyway. When asked why I was taking photos, I responded: "You'll understand later." And: "Mom would expect me to."
In the years since, I've shared and re-shared those photos with them and with our friends. And everyone is delighted to see them and remember us all coming together to wish my mother farewell, remember her and all she was to all of us. No one remembers being put off that I was making photos of the events of her passing.
None of them are great photos. But I made a small book of them, along with other photos of my mother made in the last 5-10 years of her life, and they never fail to remind me of her, of her life, of her amazing smile and heart.
The grief is inevitable and we must experience it, but we must also leave it behind ... and their memory should warm our hearts until our Time is done.
