Probibilities and Possibilities

What is the probibility that a 60+ year old grandma (me) and her 1 year old granddaughter would wear the same color sweater to the one year old's birthday party without first calling ahead to discuss sweater colors? Seemingly slim - especially since my granddaughter's language abilities do not include discussing fashion and colors. But by sheer happenstance my granddaughter and I DID wear the very same color (pink/fushia cable knit) sweaters to her birthday party this weekend. She of course looked very much cuter and younger than I. Words of wisdom on this serendipidous(sp?)occurance: clothing color choices are random acts of ageless possibilities.
