Horses are innocent

One day me and my sister went to my mom's friend's barn and I thought I could ride a horse so I did. Then my sister kept telling me that she was gonna get the horse scared and have me fall off the horse. So I told her to try. Then she came with a whip and kept trying to hit the horse with it but it kept running away. Also it was going to fast for me so I fell off. At first I was saying how it was the horses fault but really it was my fault because I'm the one who let my sister almost hit the horse. So the horse was really innocent.
