Some of my extended family (Wes and Carly for instance) were there, but not the whole horde. I remember one Christmas where there was in excess of 50 people kicking around my grandmother's house.
Apart from the normal loot collection which varies between horrid (A tartan foot warmer, how loverly) and good (scored a cd rack, which I needed badly). We were given the wrong present at one point, which was moderately amusing. It wasn't too hot to live, which it can often be in Melbourne at Christmas.
From my parents house, we zoomed off to Liz's mum's house. Happily it had cooled down by then. Christmas dinner was fairly muted, as everyone was tired, and fairly full. We sat. We zoned. It was relaxing. We played a board game about word guessing.
