I stopped and said thank you to my Grandmother

Last summer I visited my grandmother. It was her 86th birthday yet she could not remember that it was. She is suffering a disease that is prevalent in old people, Alzheimer's Disease. She could not remember my mother, my cousins, and sure enough not even me. It has been 4 summers ago since I visited her and I can only visit her during summer vacation. When I greeted her a happy birthday she just smiled and said if I was one of her apo. After the celebration it was time for me to go and after I had prepared my things, I went to my lola and said my good bye and thank you.
