No, you are not the last one. We won't put our tree up until probably the 22nd or 23rd when my daughter and her family will be here and the granddaughters can help decorate it. Also we have a new kitten and if we decorated it now, we would probably have to redecorate it many times.
We put ours up the day after Thanksgiving. It's not a real tree so we don't have to worry about it drying out and dropping needles. The last couple of years we've done the tree thing early because it's the only time everyone is home and can do it. We love doing it because we made most of the ornaments. They bring us great memories.
