I was a bit 'out of control' in my Frosh year of College. I was enrolled in the Conservatory of Music, and kinda had it in for my Cello Professor. I was a Performance Major, and had an hour long lesson with him each week. Those could be the LONGEST hours of my life if I hadn't practiced enough...Emoji...but very uplifting when I was prepared for the lesson. Early in my first year, he adjusted, very subtly, the way I held the bow, and that made a HUGE improvement in my ability to play quick notes.
I had a VERY strong facial resemblance to him, people thought that I was his daughter when we were together. Once, I was standing by his desk, he also taught Harmony, and a girl said, very loudly, "Wow, they DO look alike!" Me, with my juvenile sense of humor said, "Well, that's 'cause I been very sick, very very sick." He replied, "Well, guess who just flunked the cello".
One day, I had an "inspirational" idea, and enlisted (nagged) a guy to help me. I bought a large piece of wallpaper that had bricks printed on it. I also got tape, and borrowed a small step ladder, and the plan was to tape it over the door to his office when he was giving a lesson. The idea was that he would open the door, and see a brick wall in front of him. I thought that would be funny. Emoji Well, he heard us when we just started, and opened the door. I looked down at him, I was on the ladder, and just smiled. We quickly packed up the stuff and stole away...
Well, we couldn't just let it go, so we went up to my Piano Professors Office, where I also underwent a weekly hour long lesson, and we were successful! We got the door 'walled in', and took off. We didn't stay for the end. We heard that when he saw that he was walled in, he had his student stand back, and he jumped through the wall...a few other students were standing around...the girl he was teaching was very amused. He was a VERY PROPER German Piano Professor.
I heard that he, somehow, figured out who did that. When asked, he said,
..."I believe that it was a young cellist..."
