Though the article is about keeping your conversations private in an ever-less-private world, the reference to the English butler reminds me of my favorite character from my favorite show, Mr. Carson on Downton Abbey.
Mr. Carson is the man who knows all the dirt on everyone and is honor-bound to keep it to himself. His love and loyalty to the family he serves is beyond reproach. He seeks no personal recognition for his actions, and considers them just a part of his duties. He may just be a servant, but he is the glue that maintains the entire structure of the house. He may not be the Lord of the Manor, but he is the greatest man in the house. We should all strive to have a little of Mr. Carson in us.
