Oh today I heard one of Nannie's favorite songs on the radio.  It made me really miss our car rides together.

Oh that's so sweet. My grandmother is a great person too and I'm glad to know her.

She was a lovely lady indeed!  I miss our time together a lot especially when I hear the music she used to listen to.
