I was still lazing in my bed on a sunny saturday morning when my sister jumped on me. My father had offeredto take us to visit the zoo. On hearing this news I jumped out of bed and started getting ready for my trip to the zoo. I loaded my backpack with snacks, a camera and a few bananas for the monkeys who are my favourite animals.

We reached the zoo in an hour. We were able to skip the long que because my father had already purchased the tickets online.
