Neither of my two sons, who are ages 17 and 12, can tie a necktie. If my Army sergeant father were still alive, I would have to answer for this.
As it is, nobody seems to care, least of all my sons, who don't own any neckties to tie.
We may be nearing the end of the Necktie Age. The website tie-a-tie.com says the "necktie originated in the 17th century, during the 30-year war in France when King Louis XIII hired Croatian mercenaries who wore a piece of cloth around their necks as part of their uniform."
As fashion trends go, 400 years is a solid run.
