It's a little smaller scale, but... I've been a mid-westerner my whole life. I stopped calling soda "pop" around 10 years ago. It just doesn't sound right to me anymore.

Drink tea. Adopted from Japanese Anime.

Same with the shoes here. I take them off at my doorstep and carry them inside to the shoe rack. My floors stay spotless now as it’s surprising how much dirt they track inside.

I know some Asian cultures don’t even bring them in, leaving all the household’s shoes on the porch. I wish we did that in NA. Seems like a smart idea.

I eat mostly with chopsticks.

Wow I just posted a comment that was for another thread by accident! My apologies.

I've adopted something called Kaizen and the 5S for manufacturing which is pretty much a philosophy of making things more convenient to reduce waste, time and energy doing something and making sure items are placed in the most efficient place possible.

I used to be pretty organized and it has been great following something like this.

I got a bidet recently, and it's been a life changer. I guess they are becoming more popular now in America, but nobody had one growing up.

I never show the bottom of my shoe and think less of those who do. Learned this while traveling in Asia.

edit - Example of this is kicking my feet up on a stool at the local pub.

So many. I bow (learned from Japanese class). I wobble my head side to side, similar to South Asians, I have no idea why I started that, just feels normal now. I will often walk out of a room facing the room and close the door facing the room, learned from taekwondo. I'm sure there are so many more... I have this thing where I unconsciously mimic things.

My partner and I have KFC for dinner every boxing day (in Japan, KFC is the standard Christmas dinner.)

Look into the other person's eyes when I say cheers, chink glasses and take a drink.

I count with my thumb on my finger sections (what do you call them?) rather than my fingertips. So one hand comfortably counts to 12. (You can do a similar version, with a little more stretching, to count to 16... but I can't be bothered, and besides, I like 12.)

I say salud instead of cheers
