1. You have mastered the wipe and toss.
Not in your own bathroom of course, you’re not an animal. In public toilets, you always remember to take the toilet paper in with you before you go in, and you always remember to toss it into a garbage can afterwards. You don’t want to be that Westerner that clogged the toilet.
2. You’re not embarrassed to take a selfie anytime, anywhere.
Koreans are the kings and queens of selfies. They take out their phones on subways, in restaurants, city streets, and snap away happily. You don’t think twice about looking like a tourist or weirdo doing the same.
