Etiquette: How to Properly hold a writing utensil

I took for granted the etiquette of holding an ink pen until I saw someone holding it wrong. It was as awkward as seeing someone who does not hold their knife and fork properly. If none of this makes sense to you, then grab the latest edition of Emily Post's Etiquette. I think that was the name of the social etiquette book that my mom had me to read when I was little.

Writing utensils can include pencils, pens, chalk, etc. I have my hand turned at a different angle on this second picture. The pen should not have a lot of stress on it as you allow the ink to flow.
