Today I observed a class of the youngest students at our school. They are 6 and 7 Korean age, so between about 4 to 6 in U.S. age. The youngest (4?) was so sleepy, she could not stay awake. Even when the others got up to play a game, she couldn’t keep her eyes open or her chin off her hand.
I’m used to my adult Korean students professing they are so tired every day, but this. This is something new to deal with! So cute!
