University Experiments | Size Does Matter (1)

Hi! I'm a student of English Language and Culture. However, I'm not a native. So, please don't be mad if you see any grammar mistakes. I'm almost a near-native. Almost :)

It was a rainy morning on my way to the University. I’m in the second year of my bachelor. I got off the train, ordered a starbucks, and walked to my faculty. My dark hair was getting wet. To prevent me getting even wetter I started to run. My workout at the gym pays off. Not only do I have a fit body, I also managed to get quickly my faculty. Completely soaked I went to the toilet and looked with my blue eyes in the mirror. I fixed what was fixable, and I managed quite well. I sat down in the main hall to wait for my friends. The big clock in the centre wasn’t correct, and I went to the reception to tell them. Whilst walking, I noticed a poster on the wall. Since I took the early train, none of my friends had arrived so I went to have a look. It said a researcher was doing some research on size change. I took the poster, for I didn’t want anybody to find out but me.
