I thought that you were really weird, having a woman for a grandfather- then I figured out what you were talking about.
LOL! The result of lazy typing! GF = GIRLFRIEND!!!! Actually maybe she was my Grandfather as he was a nut as well. He would be perfectly sane and very polite all year long, but New years eve he would get drunk off his skull and run naked down the street lol! True story! That was the only time he ever drank. He would down a pint of whiskey and go crazy and forget all about it by New years day LOL!
