First things last

Today, was quite a comedy. The first was the presentations. It was either the presenters, or their presentations which were a comedy to the rest of the class. Next up, after school, on the way home, I made a fool of myself. I forgot that the boarding points of 2 buses had switched places. Unknowingly at first, I ran after the wrong bus, which I thought initially, was the "right" one. anyway, it was only after the bus negotiated a left turn that I noticed and confirmed that I was on the wrong bus! Immediately I pushed the bell, and I had the thought that some passengers were thinking of me to be a "lazy walker"... when in fact, I had taken the wrong bus. But nonetheless, I had to walk back to the interchange, take the right bus this time. So, now, I was at the previous boarding point of the bus that I had taken earlier... Normally, as long as the bus turns right, I will be on the right track. The buses which I take home will never turn left until atleast after my alighting stop...
