If you have cacti outside sometimes people are brave and decorate them along with their house... But if not then most people have Christmas trees. They cost a lot here I think because they have to be transported but most people I know get fake trees. Christmas weather is cold to us but probably nothing to northerners. Out October month can be a sweaty one. 

Oh yeah, I didn't even consider the time difference! It's 8 PM exactly here (:
