Yong-Jae, teacher is waiting for you!

I was taking register for my after school class. One boy (Yong-Jae) wasn't there. I asked the others, "Where's Yong-Jae?" and within a few seconds, Seong-Bin (boy in the middle) whipped out his cellphone and called Yong-Jae... "Where are you? Teacher is waiting for you..."

These kids are in 5th grade ... and they have snazzier phones than me!
