Conversation with my 100 year old Great Grandma

I got to visit a little with my Great Grandma while at my great uncles funeral a few weekends ago. She just turned 100 on December 27th, 2008. My conversation with her was very sweet and oh so funny! She has no idea who I am, and that's fine. It was still enjoyable to talk with her. Our conversation was as follows:
Me: Hi Grandma! I'm Debbie
GGMA: Oh Hi (with a confused look on her face)
Me: I'm Jolene's Daughter
GGMA: Oh Jolene!!! I love Jolene (Jolene was sitting right next to her I think she forgot she was just talking with her)
Me: Smiling, aka holding back a laugh.
GGMA: You have such nice teeth
Me: Thank you
GGMA: Mine are false
Me: That's ok, Do you want to take a picture?
GGMA: (after the picture was taken) I hope my mouth wasn't opened.
Me: Don't worry about that. It was good to talk with you.

Me and Great Grandma!Poor grandma her mouth was opened. But that's ok she just looks like she was talking!
