It's hard to quantify just how altruistic and not self-serving of a person she was. Everything she did was for other people in the name of love, she did not have a selfish bone in her body. You honestly could not have asked for a better Grandmother, and I'll thank her in my prayers everyday for giving me a mother who is similarly self-less and amazing.
I'm sad you are gone Grandma, but I know you'll always be right with us now. You truly are a saint.
