What's a basic skill you've taught?

In my junior year of high school, there was an event called "tie day" in which men were to wear ties.

In English class, only me, and two other guys wore ties, so my English teacher asked all three of us to come up, and show everyone how to tie a necktie.

Luckily, unlike the two other guys, I really did put my tie together myself, and I was confident when I was called first to show the class how to put on a tie.

I had a girl come up and the teacher asked me to show her, and while she was a bit rough at first, I calmly walked her through it, and got applause from the class of about 30 people. I was then asked to do it myself, and despite my introverted nature, I was confident.

I set the tie on my neck, with the wide side on my right, the narrow side on my left, I slowly wrapped the wide side around my narrow side, and pulled it over into the knot I created.

I distinctly remember one fellow student saying "BOOM!" As I tightened the tie up, and put my collar around it, as the class clapped for me🥰🥰
