So sorry for your loss ScottyRex. Your Nan seems like a lovely and smart woman. I like her illustration of life being like climbing up a ladder. Everyone only gets so far... and then they "fall" off.
You woke up in time to ask your Nan all kinds of questions. All of my older relatives died while I still believed WT/JW..org lie about people never dying. I thought I had all eternity to ask my relatives questions in WT/JW..org's New Order. Nope. Oops. They lied. All living things die...
I am glad you have wonderful memories of her to cherish.
