Lights are starting to pop up in gardens hereabouts. Because we don't have your month-long Thanksgiving/Christmas season in Oz we just do Christmas (or Chrissy, as it's fondly known) instead.
Our younger son's birthday is 2nd December so when he was a kid we always let him have his birthday fun before even thinking about putting up tree and decorations, which was then done the following weekend......regardless of what day of the week his birthday happened to be. He's about to turn 41 so no longer a child, has been living in Canada for nigh on 15 years, and we still don't put out any Chrissy stuff until after 2nd.
