Spanish presentation

Had a spanish presentstion yesterday. I thought it was a group project so I didnt really concern myself with it. The day before it was due I find out you have to do it on your own. The topic What Cant You Live Without.
I freeked out because at the moment the extent of my spanish is NO HABLA ESPAÑOL. I finally decided that giving it in german was better than nothing.
The class was broken into two groups one group in the room at a time. I was in the second group and the last to go. I gave a presentation about books/ reading. At the end my classmates asked me questions and i gave answers.
This lead to two funny situations.
That half of the class realised i speak german and stopped talking to me in english. Second my spanish teacher wasnt mad I gave it in german and said how good i did, and i realized my spanish teacher is my only teacher that knows i can speak SOME german.
