After completing a lecture on Glaucoma, while sitting at my desk in the college I noticed a sparrow. It came and sat on one of the leaves of a coconut tree just in front of my window. It was trying hard to fly. Unfortunately, its trials were not successful. I was observing this for 10-12 minutes and was wondering why it was not able to fly. I then went near the window and saw that it was having some injury and was bleeding. I restricted myself to approach the sparrow as I never wanted to scare it away. All that I was able to do was to observe. Nothing else came to my mind. After a few minutes, with its great efforts, the sparrow successfully flew away with all the freedom!
