My sister and her family are going away for Christmas. They normally do. They go to Florida. They like it there. This year she's invited my Mum and Dad. Which leaves me with a decision to make. Do we go to the mother-in-law's like we did last year, have an argument about the other half going to the pub with all the other menfolk and end up not speaking till the day after Boxing Day....or do we bugger off to Center Parcs - the kids' favouritest place in the whole world ever? On our own? Just us four for Christmas?
