My dad bought a bow tie this past weekend. Now he had to learn how to tie it. I remember a few weeks back, Strat, Jack and I were trying to watch videos on YouTube to learn how to tie a necktie. Jack finally just went upstairs, but Strat and I took it personally that it was not easy for us to master immediately and we tried and tried and tired to tie those stupid neckties. Finally, we stopped, furious, yelling and in terribly, caustic moods. It makes me laugh today.
 
Mother reported that Dad, too, went to YouTube to try to learn to tie a bow tie, with the same results that Strat and I experienced: anger and frustration resulting in a very cleansing yelling at the computer screen.
 
Here is a video of NFL linebacker Dhani Jones, a self-proclained aficionado of bow ties, showing how to tie one. There are even publications for aficionados: Doggie Aficionado, Cigar Aficionado, Toad Aficionado, Shoe Aficionado and Guitar Aficionado. There is a band, teliquia brand and book club that all bear the name.
 
This is a word to add to your vocab!
