Waaay too early but my daughter spotted a tree in a neighbours house today too!
We may not put up a tree this year as we are travelling to the inlaws. (But then again, we could just put it up early-definitely not until December though....)
Decorations have been up in the shops for quite a while now. Last year, I was in our local shopping mall waaaay before Christmas and a foreign gentleman who was obviously visiting from somewhere in Asia approached me and said "excuse me- what festival are they celebrating here?" (of course you could not tell as, for some reason, it was mainly garlands of orange baubles). I don't know which of us was more embarassed as I explained to him that it was for Christmas, two months later!!!
