Here's a video of me teaching my classmates the dance to HOTOGO by Chappell Roan, I also showed them the ChaCha Slide!
Even something as small as tally marks can be completely different in a new country, though I'm not sure I ever got the hang of Taiwanese tally marks or the counting on one hand!
In America, I can expect to be greeted with disdainful stares and purposeful throat clearing if I forget to say bless you, but in Taiwan I was often met with looks of confusion when I said it.
