I have worked with this family for years so I was dying when we were doing some snow fight pics, I told them to throw a snow ball at me, hit any part of me but don't aim for the camera, that would be bad.  I think it only happened because I mentioned it, it was so hilarious, what are the chances of a snowball going right into the lens hood, I was laughing so hard, they felt so bad, it wasn't a big deal it was just so funny since that was the only place they were supposed to try NOT to hit.  I love the expressions on mom's and dad's faces, they must have thought I would freak out.   We tried a few more times and got the great shot that they used for their holiday card.  Everyone was easy smiles after that.  Thanks guys for being such great sports!
