I was thankful that my Dad went relatively quickly in 1995 after the cancer was diagnosed as watching him deteriorate was agonizing. He had been here on a visit, having a great time with my sons and visiting Disney and all the theme parks so active and vibrant in his mid 70s...then just one year lafter I got an urgent call to get there asap and 2 weeks later he was gone.
I miss him so very much but I am thankful it was that way as I know I will see him again one day.

Praying God's peace and comfort for your mom and you KajunButterfly
