I'm sorry. My grandpa died of cancer. He was diagnosed in February and by Apirl he was gone. I was really close to him as well. That was quite some time ago, but everytime I see a picture of him I still tear up. I know that he is in a better place, and hopefully enjoying seeing his grandpa again.
That is the one thing that makes me feel better. I know he also lost a grandpa and now he is finally getting to share stories with himYou are in my thoughts.
