Victoria Vanishes! And Why Catalan People Don´t Get My Jokes.

Today was the first day one of my teachers got mad at me. I think I generated some snark during the CELTA course, but never a stern talking-down.
However, one of my jokes this morning fell flat on the culture divide, as my sarcasm gave the teacher fits.
From my perspective, it was an incredibly stupid misunderstanding, if it was a misunderstanding at all. When I accidentally said ¨libro¨ instead of ¨libros¨ (singular vs plural) to describe a bookcase (armario? I don´t remember), the teacher explained that there is no such thing as a bookcase with only one book. In my typical fashion, I mentioned offhand that possibly a very small bookcase (armario pequeno) would have only one book, and the teacher FLIPPED OUT.
She went ballistic, yelling at me, calling me ¨loco¨ in a bad way, and strongly encouraging me to use ¨realidad¨ as opposed to ¨imaginacion.¨ The teacher didnt´like it when people said ¨stupid things¨ like what I had just said.
I was very confused by this, but I think it might be some kind of different cultural appreciation for humor, or just tone. My light sarcasm wasn´t taken as such, or it was but not appreciated, and from what I´ve heard, this is in part due to Catalan sensibilities about humor.
There are two other explanations:
a. the teacher just is a tool
b. the language barrier (my bad spanish and her bad english) will never allow for any kind of understated joking.
Whatever the case, it was a stupid moment.

Victoria has disappeared. The last few afternoon programs have been done by very nice but much older women. I don´t know where Victoria went. I wonder now if she was always just a dream I dreamt, a figment of my absinthe-aided imagination.

Whatever the case, its looking my window of opportunity with her may have closed last week. Would´ve should´ve could´ve.

Lesson learned? I doubt it.
