Cruel

Why are human so cruel? Today, I witness a veri cruel act. Two boys from our school were standing outside the school. There was a cat there. At first, I thought that they were just playing with the cat. But then, I of the boys kicked the cat. How could they do that? I was so shocked at first but then I became angry. What is this? A cat is a living thing and it has feelings too! They are so cruel! I hope people don't bully any animals, even plant. We should respect them and not bully them. Please treat the animals and plants better. Thanks!
