"Death . . . is no more than passing from one room into another. But there's a difference for me, you know. Because in that other room I shall be able to see." - Helen Keller.
I am truly sorry for your loss, and my prayers are with you and your family in your time of mourning. The loss of your grandfather will leave a void in your life, but a happy memory in the heart and minds of everyone that knew and loved him. 100 years is a long time on this planet, just think of all the old friends your grandfather is reuniting with, I am sure he is receiving a very warm and loving welcome. As hard as it is to lose him, he is finally at peace; without pain and in the embrace of those who have gone before him. Remember the happy times and when things look their bleakest just remember that however long the night, the dawn will break.
with thoughts of peace and courage for you and yours,
Lauren.
