Earlier today, a dialogue:
S1: Can I just sit here for the day? Please Mr. G; I promise I'll be good. Please?
Me: I understand, but I need you in your seat.
... and, thus, we play the game I've grown to understand some kids just NEED sometimes, until he finally moves...
S1: But I don't want to sit here. I don't do well in the front.
Me: I understand, but this is your seat. And, like everyone else, I gotta have you in your seat.
S2: Haha. G, why you always saying "I understand" for?
Me: Yo entiendo.
S2: Huh? What's that mean?
Spanish speaking S3: "I understand."
