I am a newbie in this forum, and I could write a lot about how great forum this is, but I think Mel maguire said it in a better way.
About being a grandaddy:
When my father in law get hes first grandchild they asked him: "isnt it great to be grandfather" he replyed "yes this is great, but in my life I newer thought of going to bed with a grandmother"

Best regards
