I'm so so sorry for your lost. This gave me chills and tears just reading it. Your daughter's reaction is as normal as can be expected right now. Big hugs and prayers to your family!
you never know, maybe it could have been weather or an animal on the road.I would try not to say it was becuase of D to your dd when YOU really do not know. I am sorry for your loss, no one can heal that missing peice of your heart.
I am very sorry for the loss of your dear friend. However, because he had D doesn't necessarily mean that was the reason for his accident. I also have to say I'm surprised you would tell your 5 year old this, considering you don't know for sure and even if you did, what is the purpose of telling such a young child something like this?
So sorry for your loss. I know he meant a lot to you because he had walked the journey with you from the beginning.
