How to take good Christmas family photos.
Rule #1: Everybody keep their eyes open at the same time.
Rule #2: Don't say "Ho, ho, ho," during the photo shoot. "Cheese" works much better.
Rule #3: Don't wear your glasses ... and try to sit up straight so that you look bigger than the children if you're the daddy for example.
Rule #4: Fingers out of your mouths.
Rule #5: Keep your hands to yourself.
Rule #6: Smile.
Rule #7: No crying.
Rule #8: Remain seated ...
No seriously. Maintain order.
Rule #9: Know when you've lost, give up and wait for another day to try again. Just trying from the other side of the room isn't going to change much.
