One day, the day of the school summer holidays. I told my father that "I want to go to the waterfall," I said yes because I have business to do that. Post Office Then we departed Then my father drove to the post office. Dad took me out of the car and into an errand. While I was busy doing that. I went to the window of the post office. I saw ants nesting at the mango tree. When I finished my errands took me out to the falls. Then I swim happily.
