Can you go to grandma and tell her how you feel about her and maybe remember the funny or naughty things you did. Like my six year old has an invisable friend who writes on furniture, walls, floors. Did you do that? Share her life with her. When was she born, where, who were her parents and siblings, marriage, children, work? My worst fear is my work here on earth will be forgotten when I go. I want to be remembered and treasured still. Good luck.
