Aww that is a sweet story about your grandfather and your childhood.A completely off topic observation - I love that you spell my handle, "grey..." LOL My grandfather was from Dublin, Ireland. He was a professor of electrical engineering at Pittsburgh University. I spent most of my time with him as a child and he was the one who taught me how to read and write. He taught me to spell the color gray - G R E Y. Common spelling for him. Most teachers always accepted either-or till we came to Florida. I was in high school when an Englisher teacher sp'd the word, "grey," with a red marker several times over my paper. I was so confused. She made such an issue of it, I deliberately made a point of making sure I always changed the spelling to "gray," after that. I have noticed that when I travel to the northeast it's more common to see it spelled with an, "e," and friends I have from Europe also spell it with an "e." A silly thing that makes me happy.
I actually never noticed I was doing it and only now realised that you spell it differently in your handle. LOL It's just my bristishness LOL! Anyway I honestly hope you don't mind!
