Nearing the end of a class on Tuesday, I used my standard technique for filling in the last few minutes of the final class I am going to have with a particular group: I ask them what they're looking forward to doing when they get home.
"Anna, what are you going to do when you get back to Vienna?"
"I will go to the toilet."
She said this without even the hint of a smile on her face.
"You'll go to the toilet? Does the family you're staying with not have a toilet?"
"Yes, but I can't go in another country. My mother has the same problem."
Some quick quizzing from her fellow Austrians confirmed that yes, for the entire week she was here she was happy enough to piss but was entirely unable to take ein scheise. My gut suddenly ached in sympathy and I dismissed the class, horrified.
