I am sorry to hear about your loss.
It is indeed a shock. I just lost a dear friend and father figure on Christmas (from cancer and pneumonia). He was an exceptional man and kinda served as an impromptu therapist . . .he probably knew the most about me than anyone on this planet. Its odd to think about him being dead as it feels like he is still here. He had an amazing presence in life and I guess I'm just feeling the echo of that in the places he lived. Can't wrap my head around it quite yet.
