Sorry for your loss.
I lost one of my grandfather's last year. He taught me to fish. I have a lot of memories with him. Was the hardest thing I've done so far seeing him there. My 5 and 3 year old little girls drew him a picture. My 5 year old walked up to his casket and gave him the picture to keep with him. I'm so proud of them but I still get very upset for missing him.
