Pretty much all Koreans know how to squat. Professional squatters. Basically, this is what it's like. Stand up straight. Now bend your knees until your butt is touching your heals (NOT the ground). Your feet should still be flat on the ground, and you should be comfortable sitting in that position for at LEAST 15 minutes. That's squatting in east asia. At first, it's really funny. You can sometimes see people squatting while they wait for a bus or while they wait to cross the street.
Why is everyone so good at squatting? Because very often you need the squatting skill if you want to use a public restroom (especially if you're female). It's not uncommon to see a public toilet that looks like this:
So a couple weeks ago, I was waiting for a bus and there was this really cute little kid and her mom. This kid looked so young but also very alert and aware of her surroundings. She loved to smile and play little games - so I tried to make a funny face whenever she looked my direction. We ended up riding a bus and playing peek-a-boo for a bit. But anyways, here's the little girl and her mom, and they're also displaying the professional squatting. :) :D
I'm not a professional squatter... and I probably won't leave Korea with that skill.
