I Hate Walking Home by Uisneagh

One day I was in my car my mum was driving me to  school which she did every morning but I had to walk home . The car pulled up at the school gate and I opened the door and climbed out and walked up to my line I reached my line just before they went inside. At school we did the usual stuff maths, English and Gaeilge . When I was walking home some of the older classes were being rude to me. I was so cross that I threw multiple stones at them, large sized stones.  Why did I do that?
