Buying wine can be so awkward if you're a teacher. First I forgot my ID (awful!). Then my phone rang and I had to stash my basket full of bread and tofu and other good things to answer it. Then I ran into my student.
There are certain things that students just don't want to know about their teachers. Their use of toilet paper is one. Their consumption of wine is another. In the student's mind, teachers live in their classrooms. That is their natural habitat. They don't rollerblade, they don't eat birthday cake, and they certainly never buy wine. To find one with a bottle of wine is mind blowing, to say the least.
