If you're attending a Christmas party this year, here are three things you should never, ever do.

1. Don't talk about work.  We are there to have fun.  No one wants to talk shop while out having a good time.

2.  Eat before you go.  You don't want to pig out at a holiday party.

3. Resist the urge to try out your Karaoke skills.  At some parties there is singing, but leave it to the people who can actually sing.
