The fan above my head is generating noise instead of wind. I wonder mechanically how it is possible. It was dysfunctional the time I moved in. It made me experienced the hottest summery holidays ever until one day an electrician came and fixed it. Supervising the electrician was the hostel manager who suggest it may due to dust on the leaves of the fan. What her major used to be, I wondered. The time I moved out it became noisy again. Things come full circles.
