I am sorry for your loss. And I understand your grief... grief is actually a very good emotion, because the opposite, keeping grief in, is much worse for us health-wise.

It's hard right now to celebrate his life when all you can think of is the loss. But your grandmother's right... there will be things that come along to your memory -- they'll be sweet but tinged with the bitter.

I'm praying for you and your family. Peace upon you and may the good things shared with your grandparents be the memories you hold dear during this time.
