Phew. 6 out of 9 exams are over now. Two full days before another exam. Relief.
But not quite. Today, many drops of tea fell into the screen of my laptop. Some tea has gone inside the screen. The extreme bottom left part is strange. It seems there is tea in some parts and that area is bright, and there are shadows in some parts which are darker. Fixing it is a huge headache because I will probably have to go to a service center. And Apple service centers in India are not great. They might keep the laptop for two days or even more. This is a sad event.
