wow your mom sounds sweet and your sister sounds awesome!!!
my seeeeeeeeeeeeester (she is not my sister, she is my SEEEEEEEEESSSSSSSTER) is my best friend too. we look alike so she calls me mini me and we're always saying "you complete me" to each other with the little hand symbols from austin powers.
glad to hear you're off to great holiday times! hope they leave you grinning from ear to ear!!!
