Yes. She doesn't want to hurt her students feelings.

The coffee smells musky and Sarah is afraid that her students are playing some bad trick to her. "But Daniel offered to drink It instead, so It must be fine. Moreover, they are repeating students. I want them to keep on studying and being friendly with their professors. If they bring a coffee to me, i cannot refuse it. We must trust each other. Fine, I'll drink It. But if I get sick somehow, they're going to pay for this."<<It's fine Daniel, I drink it>> says Sarah, and then she tastes the coffee. "It is coffe with milk, absolutely. But there's something else. It's like salty. I don't know any salty laxative. Maybe there's no trick after all" <<Is everything ok, miss Heller?>> Asked somehow anxiously Samuel <<Everything Is fine Samuel. This milk...it's like salty>> Daniel gulped:<<Really? That must be because the new milk of the cafeteria. It Is a kind of goat milk, i didn't really understand. But if you don't like it, we will bring to you another coffee.>><<No Daniel, it's fine thanks. I appreciated your efforts to be friendly with your teacher.>> Sarah makes a big smile and touches Daniel hand. <<Listen, if you guys bring me a coffee every day, I will help you with your english studies. Do we have a deal?>> The students are very happy, and she pretended to not see them staring at her chest. "Boys are going to be boys, after all..." <<Of course miss Heller, we will bring to you a coffee exactly like this every day!>><<Thank you guys. Now sit down, we have a lesson to finish.>> The students went back to their seats laughing and jocking. "Such good boys. Come on Sarah, one salty goat coffee a day to not have them rejected this year. Is a deal every good teacher would do. They need It. And this goat coffe doesn't taste so bad after all. Maybe one day I will even like it." Sarah finished her coffee in some minutes and then resumed her lesson.
