Entiendo

For background & reference, check the post "Never Have an Argument with a Student Ever Again."

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."
