I remember when she first started to slip.
I took the kids over to visit Aunt Grace. They made a picture frame for her out of popsicle sticks. They glued candy hearts on the frame and put a cute picture inside.
The next time that we went to visit, the picture of the kids was gone. Grace pulled all of the candy off of the frame and ate them. She had one of the popsicle sticks soaking in water to get the candy remnants off.
That was the beginning of the end.
